I worked my way up through the micro rings playing Limit first, then No Limit. I'm currently playing PL($0.25) exclusively.
Anyone who thinks you can't be aggressive or bluff in pot-limit probably hasn't played much of it. Sure, you lack the ability to overbet the pot, but I think that's often a bad play anyway. Slowplaying is less effective in PL, because you lack the ability to fire off an insane river bet, but again, I think that's a bad strategy that rarely works anyway; so good riddance.
Also, at Poker Stars, I've found that I get almost as many FPP playing PL as I did playing NL at the same level. So, the bets may be capped, but the pots are just as large.
Pot limit gives me lots of opportunities for post-flop play, and I have no problem getting my big hands paid off. It suits my playing style, and I may never play NL again.
