Have you looked at Bitwig Studio? I recently switched to it from years of Logic use and I actually like it more, even on Linux (it runs on Win/Mac/Linux).

Second for Bitwig - I came from using Cubase (since '91 on an Atari) - and while it was a bit of a change, my workflow is much improved.

I think, personally, having worked at various music software technology companies, I'd prefer to try an open-source DAW if I'm going to move away, so I can modify it myself and add/modify features/UI/UX as I see fit.

Reaper then, even if it's not open a source, you can truly customize it!
