1cm is a small difference, I've ridden everything from a 58 to a 64.

Generally I find that the shorter top tube, longer stem combination will keep my contact points the same distance from each other but rotate my weight into a slightly more aggressive position over the front wheel and allow me to go lower. That makes for a better-handling bike, I think. Go up in size and shorten the stem if you want a rather more upright, relaxed posture.
