all plugins in Ardour run in the app's process, so if one crashed - you might lose the project.
But UX for MIDI editing in Ardour is so much nicer than Reaper's to my taste.
It is cheaper and better and supports Linux.
It's on flathub so you can try it out on any distro.
Bitwig has so many tiny conveniences like this that I never bothered to renew my Live license. Native Linux support is the cherry on top.
There are even projects like this that let you restore the missing parts and use it elsewhere, but it's kinda buggy: https://github.com/velkajelka/linux-native-ableton
If you mean device drivers, it can be a bit hit or miss, generally stuff works but for example I have an SSL audio interface and while the audio works, it's missing a lot of the configuration options that the Windows drivers give you around customisable audio routing.

They have a custom wine version that is built specifically to fix ableton issues on linux. I haven't tried this myself but I have heard good things about it on their discord.
For open source, Ardour but yeah...
Also if you're keen on Open Source, check out Ardour and OpenMPT. I use the latter, but still limited compared to the commercial options.
