The PokerTracker team are currently working on PokerTracker 3, which should be very good and a lot easier to use, and if you buy PokerTracker now they said you'll be able to upgrade for a reduced price.

Holdem Manager offers some new functionality but is missing a lot of stuff that's currently in PokerTracker. It's also going to be fairly expensive. Other options are Poker Maven and Poker Prospector. They have better and simpler user interfaces than anything on market, and are probably good if you don't want the really advanced stuff or huge databases, which it sounds like you don't.
