Best PC Holdem Software, Stacked, WSPO TOC, etc.

[AZGASSER]

Looking for recommendations as to the best PC computer game for learning and tweaking my NLHE game in lieu of playing online. I have read that Stacked has the best AI, not sure if there are others. What have you all tried and found to be great computer games. Thanks in advance for any help.

I like Poker Academy for no-limit (I believe the AI from Poker Academy was used for Stacked). And Turbo Texas Hold-em from Watson for Limit.
