There's been tons of editing systems that have come and gone, and I say learn all the one's that can get you work. On the top of the heap, is still Avid Media Composer, which has got me Movie gigs, Broadcast Union Jobs, and everything in between. It's still the most used in broadcast and movie work, and there's a reason for that. It's like driving a race car, it's best to know as much as you can, to drive it where you need to go. Just because something is easy to learn, doesn't make it the race car you need, to win the race. Learn it and then learn the others. You'll thank me in the END
