I tried that LMMS program and eww it looks hideous, like all things of Linux origin (not sure why). That said, my opinion should be of little consideration to you if you like it. The general consensus is that Linux is not very good for music production, though. Thankfully nearly all DAWs offer a free demo with minimal hassle, so try em out and see which one clicks with you. It really comes down to workflow, and no one can predict which DAW you'll like the best.
