Default [Q] Android tuner pro or System tuner pro?

Hey guys!

I'd like to start with that I hope this is the correct section to ask this, if not, I'm sorry.

I'd like to know your opinions about which one do you prefer, android tuner pro or system tuner pro. I never tried any of them, I only read what features and UI they have, and I've seen a couple of screenshots. And from what I've seen, they are very, very similar. Is there any actual difference between them, either in terms of features or usefullness or whatever?
