All good points. Here is some other stuff I look at when shopping tables and deciding when to leave.

Who has position on you? Giving immediate position to the tall stack (likely a good/confident player) or a marked strong (semi-loose) player or maniac could cost you big. Taking position on a strong, somewhat loose player can put a big dent in their skill advantage. Giving position to weak players, habitual 50c betters and extremely tight players can be desirable. Maybe it's a mistake, but I avoid bad seats at good tables.

How much Pre-flop raising is going on? Are players from Mid/Early position able to limp in? What's the tolerance for pre-flop raising? Does everyone drop on a $2 raise pre-flop. How many players are usually seeing the flop?

How liberally are people calling bets after the flop? Some games anything less than a pot sized bet on a small pot gets called. Others, everyone drops on a 50c bet unless they have top pair or strait draw or better. Usually a player trait, although the table seems to influence this as well.
