Ho Ho! Exactly! I used to get really cheesed off with Illustrator and Photoshop users (usually Mac users, by the way!) who sneered at anything else, especially if it was on a PC! Same when I was a photgrapher; the arguments between Canon or Nikon or Olympus fans: I deliberately bought a Russian Zenith once, just to prove the point! Which I did, but I left that club not long afterwards...
As with all crafts and arts, the craftsman or the artist is the most important factor in the equation. Imagination, skill, judgement, determination, all go towards the final success, or otherwise, of the piece. Which tools he uses are incidental; well, almost.
Hey, looking at your site, I am clearly preaching to the converted! All success to you, you deserve it.
I still use Coreldraw, and Rhinoceros for 3D work. Paint Shop Pro and Wings, as well as a few others get played with sometimes, but I'm a great believer in getting really competent with a couple of tools, rather than dabbling in dozens, however tempting. Of course, when I win the Lottery I will give up the day job and have plenty of time to get expert in all of them!
Best wishes,
