Yes the Phoenix can be clean or nasty depending on the input 'drive', which kind of shapes the aggression (or knee). It may be best to post your questions in the electronic music production forum.
I have both, and Ben has pretty much summed it up.
Mpressor is clean, super fast and punchy. Can do some really cool stuff in mixing and sound design as well.
Phoenix is thick, deep and meaty with a subtle warmth. Definitely adds that final 10%. The SC filters are essential for dance music.
