Last night I played in a 00.25/00.50 ring game, on the third dealt hand had K-Q, flop was Q-Q-5, ended up going allin won $30. What I'm wanting to know, is it better to play in ring games or sit n go's to increase my bankroll?
Sit-in Go's. You can win more in ring games, but sit-in-go's are (generally) the safer bet - you won't win as much at a time, but you also don't lose so much when you do lose.
It depends what you want to do and what you're strongest at. Some people are better tournament player and some are better at cash games.
It's kind of a risk/return thing. You can certainly build your BR faster in cash games but you have to be willing to get through the bigger swings in your BR. SNGs are generally more consistant if you have the time and patience.
Personally I prefer cash games unless my BR gets less than a few buyins.
