As the title implies I am confused about the electrical characteristics of N channel depletion FETs vs P channel enhancement mode fets. Won't both of these devices act similarly as they both have negative threshold voltages? Thanks!

Although both have negative threshold, the operation is still opposite. For N-channel, the gate voltage must be above the threshold voltage to allow conduction through the channel. For P-channel, the gate voltage must be below the threshold voltage to allow conduction.
