I used to mind the height difference, but now not so much. And I do like that teens and adults share the same wardrobe, because at least I won't have to dress my sim again when he ages up, and I won't find a CAS item for adults that's not available for teens. That one's a huge disappointment in TS3. I still have a lot of shirts from my high school days that fit me, so it's not completely unrealistic.
