Properly staffed, I don't know how it could be different based on the equipment. There is one factor that can make or break the level of enjoyment in your schedule that I can think of. Since the 200 has a greater number of airplanes, your chances of flying with douchebag captains I feel is slightly less.

I only feel this way because there are ALOT of very senior, crusty, nasty captains on the 700 and they are well known. Most F.O.s will avoid them like the plague eventually leaving it up to the reserves to fly with them. Especially when PBS comes on line since it has an option for F.O.s to select crew members they don't want to fly with. Guess who will get stuck flying with them besides the junior FOs.

As far as trips, layovers, pay, etc I don't think it matters which aircraft you are on. Once they are properly staffed, it's fair game for the most part.
