Depending on needs, I don't think it's necessary to commit to the big boys, as long as you DO commit For somebody doing simple mixing, editing and recording, many of the smaller daws will work perfectly fine.
I agree that Harrison is a poor DAW for workflow. It also crashes a lot. BUT it is the best sound of any DAW I have used for mixdown.
So I do all my editing and automation in Ableton then I import my mix into Harrison as stem to add some tape compression and a bit of mastering EQ. I think it sounds really good. No matter what I do in Ableton with tape compression and mastering plugs such as Waves or Slate etc I can't get close to the open and warm sound that Harrison gives it with very little tweaking. Seriously I couldn't believe it myself.
If you think about it Harrison have more experience making consoles than other DAW makers so they have all that dithering and gain staging stuff sorted.
