I have virtually every DAW installed on either my Windows or Mac computer, know them well, and could run a session and mix with any of them.
Each DAW has strengths and weaknesses for particular applications, and I choose what's appropriate for the project at hand. In my world, Sonar gets the call
far more often than anything else.
I think of each DAW as a session musician (I used to do a lot of session work back in the day). There was always the hotshot guy who could do something really amazing and would get the call sometimes, but most of the time I wanted to work with the player who showed up on time, could play just about
anything really well, smiled a lot, was liked by all the other musicians, and made the sessions run creatively and smoothly
