I feel like
Paulina is more "modern," and by that I mean more old-fashioned and more ready to make a comeback. I personally prefer the Russian
Polina (pah-LEE-na; unstressed O sounds like A in Russian), but
Paulina is nice as well. I think
Pauline is still a bit too dated for me. I equate it with names like
Shirley and
Bernice.
Combos later... I have to run to lab.
