I've had PokerTracker v2 for about 3.5 years, but I am now looking into either upgrading to PokerTracker3 or purchasing Holdem Manager. PT3 would be $79 and HEM is $80, so clearly the prices makes no difference.

I've spent a lot of time playing FLHE FR, SNGs and MTTs. Now I am focusing on NLHE FR and would love to have a HUD which I believe both devices offer.

From people who have used one or preferably both, which would be a better purchase and why? What are some positives and negatives about each?
