depends on how much you carry during the day or on a daily basis.
if it's alot or more than the usual haul of wallet, agenda, sunglass case, and maybe a couple of makeup pieces..then city!
if you carry around wallet, agenda, sunglass case, makeup bag, magazine or book to read, snack, water bottle, ipod, and other odd essentials then the work!
goodluck! and please post pics when you decide.
