Poker Stat Software - PokerTracker vs PokerOffice

[dark_horse]

Is there any point in using both of these programs? I'm starting up a new account and bankroll and wanted to start fresh by also beginning to track my play on PP. I have been using PokerStat over the last year for my ring games (less than 3000 hands) and tourneys on PokerStars, so I was hoping I could import the data from there.

I know PokerOffice has some slicker graphics (and website) and real-time hand analysis and odds charts (I don't think PokerTracker offers any real-time features - please correct me if wrong), but I've also heard that PokerTracker goes a bit deeper in stat analysis. I know PokerTracker supports many more sites currently than PokerOffice (which mainly supports PartyPoker), but I'm planning on playing mostly on PartyPoker, so this is not an issue for me. Also, if one were using PokerOffice regularly, is Texas Calculatem redundant? Any input welcome.
