I think the Trooper might be my favorite, though his non-com is pretty nifty too. Nik Sant is the "dull" of the group... Like his backstory as a pathfinder though, not a regular trooper, so that's interesting.
Still, there's room for improvement all around with them I'd say too... I'm gonna do a little customizing to my group actually to make them more realistic w/gear, but at the end of the day I loved the bundle set. They look good together. I doubt they do too many more like that bundle of 3 though.
