I play 4/8 and 10/20 a couple times a week. While they are both beatable, I find that they are about equally profitable for me despite the gap in bet sizes. I attribute this to more multi-way pots at 4/8, but it could be too small of a sample at 10/20 or lack of skill becoming more evident at higher levels.

10/20 is by no means a rock-garden, but it definitely contains far more tag's and tp's than 4/8 (or 20/40, from what I hear). But if you're aware that your opponents are tighter and adjust your game accordingly, the game can be pretty profitable.

I think, in short, you really can't go wrong!
