I run Gimp in Ubuntu 14 but am not crazy about it, I haven't tried Therapee yet but I have seen it as available.
What is anyones opinion about running programs from the cloud vs. getting a standalone program and installing it on your own computer?
I'm no fan of pay per month. I started with the Lightroom standalone version and an old copy of Photoshop but after trying to get a new standalone copy of PS, and failing miserably, I decided to look for an alternative.
I tried several editors and fell in love with RAWtherapee. The versions I started with were good but the latest versions are beyond good. I deleted LR on my Mac and combined RAWTherapee with GIMP for quite some time but GIMP never was a jolly affair. I simply dislike GIMP; working with it feels wrong. After Affinity Photo was released I happily deleted GIMP and do all the fine-tuning and specials in that program.
I now do all my work for an investment of 40$. Once. That's how much Affinity costs (only Mac).
Basically it boils down to your expectations of a RAW editor (and image editor) and how much you are willing to pay and under what conditions.
I personally don't mind paying a 1000$ for a standalone but I'd rather drop dead than pay 10$ each month. Others find that strange and prefer the opposite.
