Chessmaster = piece of buggy software, with no support, online play wich is a joke, absolute useless analys function.
Fritz = Chessprogram usefull from amateur to profesional, join online server with 7000 other chessplayers, best analys function you will ever want 100 times as many options that compared to chessmaster.
You can find a review of both programs here, you might have to go back some pages.
