every producer I've known, or known of uses or knows how to use protools. People can argue back and forth about whats better, but plan and simple protools is the industry standard. Thats not a statement as to the quality of protools over any other app, it is just a fact. In professional facilities you will always find protools unless it is a 100% analogue situation, which I think I can safely say the chance of anyone coming across in a urban music production situation, is extremely rare.
