High variance games - SNGs, FL FR, NL BSS, NL SSS
extremely high variance - FL SH, NL SH
fucking insane variance - HU (all formats), MTTs, Omaha
I have played all of these games and statistical variance is always high, but there is a difference in the way they affect you psychologically. Playing HU the variance had me nearly ripping my hair out for example, while with SSS you dont really notice it so much - partly because you can play so many hands that it evens out quicker.
