Although the newest iterations of it aren't to my liking (cloud storage and rental fees) I still think that for live recordings Pro Tools is still the simplest and most flexible live recording DAW out there. What it does it does well and once you get some of the shortcuts down it's really fast to edit with. I don't think it's the best compositional tool out there, but doing multiple takes and the comping features make it stand out for me. If you do a bit of film scoring there is a precise editor for adding sound to picture too.
The other thing about Pro Tools is that pretty much every studio will have it. If you compose your music in another program you can always put the stems into pro tools after and pretty much be guaranteed to be able to record, mix or edit in any studio you go to. Not saying that Pro Tools is the best, but it would be a good idea to learn it or own it if you want to take your music to someone else studio. Pretty much all producers and engineers that I know know how to use it whereas the same can't be said for pretty much any other DAW.
