Holdem Manager vs. Poker Tracker?

Ive been using the trail version of PT3, which just expired. I was going to buy the full version, but have seen alot of posts mentioning Holdem Manager.

Any thoughts on which one is better? I'm on the position to purchase one, but not both.

Thanks

The search function is there for a reason. This has been discussed several times.

Sorry...guess I'm getting lazy in my old age.

I havent had much success with Poker tracker trial version. Then again, my computer is on the crapper here lately!! I will check out the thread for this since it has been discussed already. It seems it would have to help for online play. THanks!
