NOTE: Everything I’m about to say has one huge caveat (more on that later)
Pro Tools has garnered a reputation as being unstable in recent years. IMO largely because peoples setups are bad. I use it and rarely have any issues. I can’t tell you how many times I’ve seen Pro Tools bashing on various forum that start with someone complaining that they’ve had it with Pro Tools, then you look at their rig and it’s a 2004 macbook with a single hdd and 2gb of ram. AVID also has a list of system tweaks that you should do but most don’t.
Anyway, enough of that.
DAW choice really should come down to work flow and what best suits your needs. If you are thinking of changing DAWs or are just starting out and looking for a DAW, I would make a list of the things you really want most, for example, I’m guessing if you’re on this forum you probably want a good MIDI editor, and start with that. There’s a lot of DAW that you can trial and see what you like.
Now for the caveat. If you want to work in the film or television industry you will most likely have to deliver your cues in Pro Tools format. This doesn’t mean you have to work in Pro Tools, there are lots of composers working in other DAWs, but it does mean that you will probably need to own a copy in some form and know how to use it well enough to get the job done. There is a free version of Pro Tools which I haven’t used which seems like it would be fine to deliver cues as long as you didn’t have a lot of stems.
