I've been on FL, Reason and now for the last 2 years or something on Logic that is awesome. I didn't like Ableton, but that was just more about how it looks like and not the actual DAW itself. Reaper seemed too thin 3 years ago.
If you want a decent alternative, there's Cubase, which many "long-term-gotta-try-every-piece-of-audio-equipment-in-the-world-first-and-then-pick-the-best" type of musicians like Noisia and Rob Swire use.
Thing costs like over 500 bucks however. I haven't tried it because I know I couldn't buy it atm even if I would end up liking it.
