Poker Academy Pro and Turbo Texas Hold'em

Hello,

I am pretty new to poker. To improve my playing I read books, forums and play online for very small stakes.
I now want to buy a software to help me improve my playing. Two systems seem to be the market leader: Poker Academy Pro and Turbo Texas Hold'em.
I tried their demo versions but could not really decide which one is better in regard to strength of playing and the quality of advice given. These are the main criteria for me, the quality of the user interface etc. are not so important to me.

Could you share your knowlege about these programs and especially a comparison of the two?

Thank you.
