PMOS carrying more current than NMOS?
In your NMOS case the voltage source is mentioned correctly with the total current but in the second PMOS image it does not match. And also the Vgs of both should not be same because for the PMOS Vsg refers to a positive threshold. Try this, connect the ground that is in your image which is connected on top(source) to the bottom which is the drain (Symbols are reverse in PMOS compared to NMOS I hope you are considering this, the top is Source and the bottom is drain unlike in NMOS).

Make sure your PMOS source terminal  is connected to a +ve voltage and your drain connected to the -ve of both the voltage sources(gate and source) and place the gnd at the bottom of the PMOS which is the drain. Now you should measure a current less than the NMOS case because mobility of holes is lesser compared to the mobility of electrons.
