Poker definitely hasn't been easy for me to learn, and i've tried a bunch of training sites, books, etc. i think the trial for LB is kinda limited, but will give you an idea of what it does. I'd say just do some reading or watch some vids on whichever one you are interested in. i've said before the video content is worth the price alone IMO. full length video content that corresponds with the leaks you are displaying, etc i used PT3/PT4 and bought it for that, but then changed to HM2 and ended up buying it for HM2 as well. It really goes thru your database pretty extensively, and gives you info on everything 3bet/4bet pots, Preflop/Postflop, biggest losses, trouble hands, position. Where Leakbuster is a completely separate fully functional software program or i guess an app if you use HM2. it gives you some general stat ranges, and will give you a good/bad grade. I'm not sure which one you are referencing, but Leaktracker for PT4 is something that is included in the program and isn't meant to be used for extensive database analysis.
