Actually, hobbyists will always be hobbyists until they acquire
professional levels of skill *and* put themselves to the test of
performance and/or distribution of their material. The gear they use
will not elevate their skills one jot. Owning a guitar does not confer
ability upon the owner.
I will say this about modern music technology, regardless of platform:
It makes a lot of bad music sound much better at the surface level.
  However, in my case, I've found Linux Audio very
interesting to learn
 a lot about the audio software implementation (obviously because of
 the open source mentality) and also for understanding what kind of
 things can be done (for a user/developper point of view). But for
 productive work I simply can't recommend it because Pro Tools,
 Reason,..., and a huge availability of VST plugins are too far from us. 
Strange, I use VST plugins with Linux quite a lot here at Studio Dave.
Ardour seems to work pretty well for me too, and its price point is more
attractive to me. ;)
Best is to use what works for you to make your own music.
You can also thank whatever gods you believe in that M$ didn't make the
WAV format as proprietary as the DOC format...
Best,
