I don't hate plastic or the trigger dingus safety (e.g. Glock), but all equal I do prefer metal and a manual safety. Otherwise I agree 100% with everything Skans said. I absolutely love chambers with the little cut-out so you can actually see chambered brass.
Anything might be a carry gun so smoothness all-around is nice, sometimes called a "melt" treatment. But yeah, for a concealed carry / backup gun small size is more important than capacity.
