Variance depends a lot on game conditions and your playing style as well as what game you're in, but here are some ideas:

Is a strong hand typically a big favorite (draw poker, deep money NL holdem ring games) or a slight favorite (Omaha high, razz, NL holdem tournaments)?

Does a lot of money go in before hands are really defined? (games with a lot of early raising have much higher variance)

Split pot games usually tend to have lower variance than single-winner games. The fact that you win pieces of a pot more often more than makes up for the fact that you more often have two players driving the betting on later streets instead of just one.
