software question from a newbie

[JeffBB]

Hiya all,
I'm a new member so excuse me if I ask something that was asked before - haven't find it so far.
My questions is - I'm now facing a problem which software to choose and my two main options presently are Pokertracker and Pokeroffice. Can anyone help me with a choise I need some comparison of the two or something. Or maybe you can advise me some other software, that will be most appreciated.
Thanks,
Jeff
