I don't have a favorite magic creator, or creators, for that matter. I perform with my own style, and there are some effects out there that fit me perfectley - regardless of creator. I know of some stage performers who simply created an awesome close-up effect, and vica verca. It's about the magic, not the creator.
Sometimes, my favorite creator is myself, sometimes it's the 10 year-old on YouTube, and sometimes it's a big name like Garcia or Houchin. It all depends on what style I'm currently into, and what else is available.
While some artisists have a great reputation, it honestly doesn't mean that their magic is any better than that of a creative 12 year old (and believe me, I know some insanely good and creative 12 year-olds). However, the 12 year-old will not be able to have the same success as the credible artist, simply because of experience, even if his effect is better.
To stay in line with the topic, I guess I have to pick a favorite. I don't really have one, but currently I am really enjoying all of Wayne Houchin's stuff. It is all simple, and hits the hardest of most anything I know. Of course, there are others, but currently, I guess that my favorite magic artist is Wayne Houchin (it is constantly changing).
