I was also a SCORE user for years (Prof. Leland Smith, now deceased) but that was DOS based, now redundant unless you want to use DOS BOX, which I can't be bothered with frankly!
I mostly use Pro Tools, because I really like its editing and recording interface. It drives me crazy at times, because, at least on my Mac, it's kind of glitchy. I'm also not thrilled about the imminent switch to a subscription pay model. I've toyed with the idea of moving to another DAW, but there are aspects of the Pro Tools feature set that I have not been able to find in any other software (for example, the Clip Gain line), and am very dependent on in my production work.
If I were doing a lot of electronic music, I would probably use Ableton Live, which is an amazing program and incredibly stable. I have also recently discovered the Project Page in Studio One, which is a great mastering environment.
