I agree with bbtuna 100% about the scoring markers. I left the old wooden ones on the table despite the fact that they sent me the new ones with the upgrade kit. Nobody I've shown likes the new markers better than the old wooden discs (except my then 4-year old because he was just learning to read numbers and they reminded him of counting blocks - now he's 5 and likes counting the wooden discs).
There is just something retro/tactile about the wooden discs and the feeling of slamming them across when you've won the game. Everyone loves doing that. Keep score whichever way works for you, but I think most players would vote for the old style discs.
