Theoretical question - which game would you play? All else equal:

Game number 1 - has 2 players (including you) and a slow dealer. You will get about 100 rounds per hour.

Game number 2 - has 5 players (including you) and a lightening fast dealer (the "best in the west"). You will get 120 - 140 rounds per hour.

Which game?

We all know crowding is bad. But is it purely because of the presumably slower game speed or is it because you are less likely to get the good cards in the high counts?
