I prefer OS for the cost factor, but hate the look of rise snaps, that's why we use FB and charlie banana. But with the size of my DD if we did sized I would only have needed NB, small, and medium, so really only 1 more set of diapers, not too bad. So really I don't think it made too big if a difference cost wise.
One of the things I really like about the OS is that I will be able to use the same diapers on my toddler and the new baby (when they grow out of NB dipes) ill just need to resize them. It will save me tons of time with shopping and shipping. If course some people already have all of their sized stash fron previous children and are in that same boat.
I've gone back and forth on this, maybe the only reason I like OS diapers is because I started with OS diapers.
