I like the really big ones, and the really small ones...really depends on the razor. Overall, though, I think 6/8 is just about perfect. Small enough to control, big enough to have some real heft. That being said, I like them from 6/8 up. It's hard to choose, really, because it really depends more on the overall design and execution of the individual razor rather than its size. If you like it, get it. If you get it and don't like it, there's a great resale market.
