"The real question is: are you good enough to use stock plugins?"
Sometimes these are embarrassing. It's like seeing a kid who can really play his Squire Strat and you know some chords that you play on your LP.
I think Live users seem to use built in stuff the most. Youtube is full of videos using the 3xOsc. I have so many toys for Reason but so many people cranked out stuff using Reason 4,5.
