I've used Garage Band, FL Studio (6 was the last version I've ever used), Acid Pro, Cubase 5, Reaper 4, and in my opinion Ableton Live stands at top of my list.
I've been going back to Ableton for everything I do between recording bands, simple vocals, to elektro/house/dubstep.
But this isn't a which DAW is better thread. Each are better suited to those that know how to use them.
Now I did some searching regarding discussions on Ableton, but only a few specific threads from a while back.
So, if you're usingit and you have some questions, ask away!
