Renoise if you love trackers. Reaper is an amazing budget DAW, and Bitwig Studio is the closest you can get to Abelton on Linux. Personally, I like Bitwig Studio.

Sadly, other than Ardour, I am not familiar with FOSS options, but the three I mentioned above are very good.

Septabee better get mentioned at some point.
