1. no real conclusive thing on this, i think. if you're looking to get better at poker in the long run, you should probably move up if you have the bankroll. higher ptbb/100 is not significant until you reach a LOT of hands. you don't exclusively have to play 3/6, either, a lot of ppl play ranges from 3/6 to 10/20, whenever they feel the game is good enough to play.

2. live 2/4 games are a joke. ppl love calling, so playing a little more loose with speculative hands in position is always profitable (and more fun). online, ppl are more aggressive and less calling station like, you have to play better fundamentally overall.

3. stick with the style that you feel most comfortable with playing. either style imo can do well at these stakes.
