I've got no axe to grind either way. I've used Cubase and Logic in the past, but had Sonar as my main daw for the last 6 years because it was a bit of a babe... the look of the interface and the workflow just suited me.
I was frequently frustrated with instability and crash issues, but that was true with other daws as well.
I went for the Samplitude deal because I've wanted Spectral Layers and the general audio-editing capability for while but couldn't afford it. Samplitude is a very good daw, but I'm finding it just doesn't suit me in terms of laying down material in a way that keeps my inspiration going, but thats just me and my foibles.
I had tried Reaper a while back, and didn't take to it. I guess I also bought into the general perception that it was the cheap option and lacked the investment to make it a functional competitor to the rest.
Well I've looked at it again, and even although there may be a "love-in" to a degree on this forum, I can see why people become advocates for it - it deserves a lot more credit than it gets even now.
Its stable, fast, and efficient, and it has most of the features I'm looking for and a good bit more - ARE would be nice, but its coming. At first glance its ugly and cumbersome, but its meant to be lean - there are some beautiful skins out there and and it can be easily customised to give you the workflow you need.
I'm not a pro, but I have been working with these tools for many years, and Reaper deserves to be taken very seriously indeed - especially at £60.
As I said elsewhere, Reaper comes as a tramp to your door - dress it nice, talk to it and get to know it and - imo - you'll be richly rewarded
