If I was called in to pilot a session on any DAW, and I mean
ANY DAW, I could do it. I've used all of them and am quite familiar with how they work.
They all have different strengths and weaknesses.
The object is to choose the DAW whose strengths match your needs, and whose weaknesses don't impact what you need to do. In terms of crashes and bad behavior, in my experience much of that is due to variables in the Windows environment, coupled with how someone uses a program. And frankly, I think
a lot of it is just plain dumb luck. Program A might not be happy with build 6.003.455.1 to a particular graphics card while Program B might not care at all. But when build 6.004.556 comes out, Program B might crash while Program A works fine. And if you don't use that particular graphics card, then everything might work. Or nothing might work
My biggest problems with reliability have related to graphics cards and drivers, with the second biggest being defective RAM chips (not defective enough to fail, but enough for a few missing bits here and there). I think the latter problem is more common than people realize.
I've had very stable operation with X2, but also with Ableton Live 8, Pro Tools 10, Cubase 6, Acoustica Mixcraft 6, Sony Acid, Traktor Pro 2.5, Samplitude Pro X...you name it. I attribute that to the choice and testing of the hardware (it's a PC Audio Labs computer) rather than to the software. I've had very good luck with ADK and Rain computers as well, and given those experiences, I'll stick with computers that are integrated by people who are a lot smarter than me
If there was only one DAW left in the world, I would use that and make music with it. I wouldn't care if it was Mac or Windows, either. Fortunately, we are not in that position.
