Haven't played it yet, I think it is very exciting, learned to play it here in CC! Different strategies compared to NLHE because strong pre-flop hand doesn't mean you have a huge chance of winning the pot.
I play PLO and PLO8. I like them both! For beginners that come from NLHE, it's definitely an interesting feat and learning experience. Both of which can be learned quickly, but mastering takes a while.
I like PLO, nut prefer PLO8 as hand selection for me here is infinitely easier for me. What I don't like about either are people who don't play it often enough to understand that it is a drawing game, and massive preflop aggression is often pointless because no matter how good double suited AAKK looks, you miss many flops with it, and the nuts change from street to street.
