to answer your question about what has more/less variance, it has to do mainly with the number of cards being delt,

this statement is pretty misguided imo. the number of players, the betting structure, and other rules all play a huge roll.

compare razz, 7stud, 7studhilo. now compare each of these heads up vs 8 handed.

now think of some crazy variants of poker, 10 card stud with one betting round vs 7 card stud with 5?
