i use VEGAS for my own videos.
I find it REALLY easy to use and quite intuitive. but i started writing music on sony ACID and they are so similar...
my mate has final cut pro - there are a few tiny things he can do that i cant without addons in vegas, but 99% of teh stuff i can do but FASTER and EASIER than he can.
MUSCULARTEETH - Many things, mostly to do with Art.
