I'm really tempted here. I've got a paid Ableton license, and I absolutely love Ableton, but it's the main thing keeping me from dumping Windows 10 for Linux.
Transitioning between Ableton and Bitwig is seamless from a UI standpoint. They have essentially the same controls.
The only thing that isn't great moving from Windows to Linux for production is your VST ecosystem becomes much more limited. Running plugins under WINE is alright, but if they're heavy you'll run into latency issues. There's a sizable collection of plugins that are native under Linux though[0]. I've used many of these with great success.
You can get pretty far with the built in instruments and effects in Bitwig, especially with the new modular grid. I haven't felt much need for third party stuff.
