From my experience there are few things to think about both things:
I. RDL reports are HOSTED reports generally. This means you need to implement SSRS Server. They are a built in extension of Visual Studio from SQL Server for the reporting language. When you install SSRS you should have an add on called 'Business Intelligence Development Studio' which is much easier to work with the reports than without it.

Benefits of RDL reports:
- You can host the reports in an environment that has services running for you on them.
- You can configure security on an item or inheriting level to handle security as a standalone concept
- You can configure the service to send out emails(provided you have an SMTP server you have access to) and save files on schedules
- You have a database generally called 'ReportServer' you can query for info on the reports once published.
- You can access these reports still through 'ReportViewer' in a client application written in ASP.NET, WPF (with a winform control bleh!), or Winforms in .NET using 'ProcessingMode.Remote'.
- You can set parameters a user can see and use to gain more flexibility.
- You can configure parts of a report to be used for connection strings as 'Data Sources' as well as a sql query, xml, or other datasets as a 'Dataset'. These parts and others can be stored and configured to cache data on a regular basis.
- You can write .NET proxy classes of the services http:// /ReportServer/ReportingService2010 or /ReportExecution2005. You can then make up your OWN methods in .NET for emailing, saving, or manipulating SSRS data from the service directly of a Server hosting SSRS reports in code.
Programmatically Export SSRS report from sharepoint using ReportService2010.asmx
Downsides:
- SSRS is kind of wonkey compared to other things on getting it up fast. Most people get confused by the security policy and designing reports as an 'add on' to VS. SQL 2005 = VS BIDS 2005 , SQL 2008 = VS BIDS 2008, SQL 2012 = VS BIDS 2010(LOL).
- Continuing on 1 the policy for security settings IMHO are idiotically overcomplex. There is server security, database security and roles, two security settings on the page hosted for the service. Most people only set up an admin than can't get in and wonder why other users cannot. Most common complaint or question on SSRS is related to getting in generally from my experience.
- You can use 'expressions' that will supposeduly 'enhance' your report. Often times you do more than a few and your report goes to a crawl in performance.
- You have a set amount of things you can do and export to. SSRS has no hover over reporting I know of without a javascript hack.
- Speed and performance can take a hit as the stupid SSRS config recycles the system and a first report can take a while at times just loading the site. You can get around this by altering it but I have found making a keep alive service for it works better.
II. RDLC reports are CLIENT CONTAINED reports that are NOT HOSTED ANYWHERE. The extra c in the name means 'Client'. Generally this is an extension of the RDL language meant for use only in Visual Studio Client Applications. It exists in Visual Studio when you add a 'reporting' item.
Benefits of RDLC reports:
- You can hookup a wcf service much much much more easier to the dataset.
- You have more control over the dataset and can use POCO classes filled with Entity framework objects or ADO.NET directly as well as tables themselves. You can monkey with the data for optimization it before binding it to the report.
- You can customize the look more with add on's directly in code behind.
Downsides:
- You need to handle parameters on your own and while you can implement wrapper methods to help the legwork is a little more than expected and unfortunate.
- The user cannot SEE the parameters in a 'ReportViewer' control unless it is in remote mode and accessing an RLD report. Thus you need to make textboxes, dropdowns, radio buttons on your own outside the control to pass to it. Some people like this added control, I do not personally.
- Anything you want to do with servicing the reports for distribution you need to build yourself. Emailing, subscriptions, saving. Sorry you need to build that in .NET or else implement a proxy that already does that from above you could just be getting using hosted reports.
Honestly I like both for different purposes. If I want something to go out to analysts that they use all the time and tweak for graphs, charts, drill downs and exports to Excel I use RDL and just have SSRS's site do all the legwork of handling the email distributions. If I want an application that has a report section and I know that application is it's own module with rules and governance I use an RDLC and having the parameters be smaller and be driven by the decisions the user made before getting to the report part of what client they are on and site and then they usually just choose a time frame or type and nothing more. So generally a complex report I would use RDL and for something simple I would use RDLC IMHO.
I hope that helps.
I'm using SSRS 2005 - I think this part of it works in the same way as 2008.
As far as I can tell, you can't have folders within projects, but you can have multiple projects within a solution.
To create a new folder, right-click on the solution in the Solution Explorer and select Add>New Project...
Type in your new Project Name (eg. MyProject), and select Report Server Project from the list of Visual Studio installed templates. Click on OK, and your new Project should appear at the end of the list of projects in the Solution Explorer.
(There are other ways of setting up a new Reports project, but this seems to be the quickest.)
If you now right-click on your new Report Project and select Properties, you can see the TargetReportFolder, which will default to your new Project Name (eg. MyProject). When you deploy reports from SSRS, they are deployed to this location. (You can change the location, if you wish - I find it easier to keep track of what's going where by using the Project name.)
You will need to copy any data sources to be used in each project, into the data sources folder of all projects that use that data source. By default, OverwriteDataSources is set to false, so when you deploy a new report, it will use the data source already deployed to the Report Manager environment.
So to get the Report Manager structure that you want to see:
- Create Projects called Folder A and Folder B
- Move/copy Report1 into the Reports folder in Project Folder A
- Move/copy Report2 and Report3 into the Reports folder in Project Folder B
- Move/copy data source DEV into the Shared Data Sources folders in Projects Folder A and Folder B
- Deploy your reports
Don't forget to check your changes into source control.

If this is for internal facing users, you can just use the functionality of the Report Manager website.
You can control user privileges with roles; the default Browser role will allow users to view items with a low level of access.
If you want to integrate SSRS reports into an external website, you can use the ReportViewer control to connect to a Report Server and render reports.
To get the names and locations of reports on a particular Report Server, you can access the Report Server Web Service, and call web methods like ListChildren to get an idea of objects in the Report Server.
