Bigwig Studio is made by some of the original Devs of Ableton i believe and from what I've messed around with it in a trial. It's way better (stylish too). If I was less of an occasional dabbler in music production I'd absolutely pay for this. Linux is not a second class citizen to them which is great, any VSTs they release themselves always work on Linux natively too.
Theres also reaper, but I feel like the barrier to entry on that one can feel a bit daunting. It never feels just ready to go for a newcomer.
Theres also a bunch of different trackers that are Linux compatible some with VST support too, but that's a very different way of making music from the traditional DAW.
