Tbh, I only like the under screen FPS for the cool factor. It will be nice for unlocking when the device is on a table, or in a car mount, but generally I like a rear mounted FPS for ease of unlocking when holding the device. I guess it might just be a matter of getting used to it though. In theory, your thumb is ready to use the screen when holding, so should be easily reaching the FPS. With a rear, it lines up nicely as you take your phone from you pocket, you unlock then adjust your hand position to use.
Face unlock could be interesting as by all accounts it is very good, works even from holding your phone down near your waist.
