Which will have the least variance ?

I don't have large samples of my own tournament records altho I feel I to do better in tournaments in comparison to ring games. I do alright in NL ring games but it seems like variance can hit hard sometimes..
So I'm personally looking to dedicate my BR to
one thing..as I typically move back and forth between ring games and Tournies..
I read past threads with tid bits here and there some ppl say limit has worst swings the NL, and Sitngo's have high variance as well.. looking for others experience etc.. discussion on it.. the Poll is set for 2 picks for people that think both of either ring or tourny.
