I tried both and i have split answer.
I owned cockx suites back on PQR and PE so im quite familiar with them. Got TuanHA's warrior Patron edition just recently.
Both have similar performance dps, pressure and zerging wise and both rotation in said parts are flawless.
Its kinda down to personal choice. I got all of TuanHA's routines as a gift from a friend who decided to pause till WoD, i personally would not invest that much money in complete suite. I agree that TuanHA is not so much supportive as i think he should be, not that any of those two routines needs any updates as both of them are doing job flawlessly, just to be polite. Cockx on other side, as i followed him around as he moved, i like him, hes supportive and overall pleasant for support and questions.
Bottom line is, no matter which routine you choose you wont go wrong. Both of them perform on pair and equally good with a lot of options to config routines how you like, its down to your preference.
With WoD release date coming close, i would rather ask/research which of them would be updated first.
