I use both PT and an excel spread sheet. While there's nothing better than Poker Tracker analysing your game I find it lacking as a banroll manager. Here's why.
While it works great for cash games, many sites require you to download Tournament and Sit-n-Go summaries.
If you accidently close down a table before the Auto Import records the hand, that information is lost.
It doesn't track your live sessions or other live expenses like rakes, dealer tokes, gas, books, transfers etc.
It doesn't track ALL variations of poker. I play mostly Hold'em so that's the version I own. You can get the Stud and Omaha versions, but unless you play those games alot, it might not be worth it. Some sites offer Draw or BlackJack
. I suppose I could use my spread sheet for those as well.
