When a FET is turned on properly, there will be no voltage 'lost' across the FET while driving the load (well, virtually none if you want to be really picky).

That is not the case with "normal" transistors, which work differently and will have a voltage drop across the component itself like you mentioned.

Among other things it's one of the reasons why FETs are particularly awesome for electronically driving and controlling motors. (For example it's in all the even slightly-modern stuff for the RC crowd, and those guys take this stuff seriously :O )
