I am having to decide between a MSOP package and a QFN package for a Buck controller that I am designing in. The Part number is LTC3603. The MSOP is called an eMSOP. I cant locate any further information on what is the difference between MSOP and eMSOP. What are some of the pros and cons of each package. Right off the bat the big flip side of using a QFN is the lack of ease for rework. A MSOP is leaded and hence can be replaced easily without a hot air rework station.

\$\theta_{JC}\$ and \$\theta_{JA}\$ values are given in the "Pin Configuration" drawings on page 2 of the datasheet.
The QFN package has lower values.
