I agree with everything Richard Sanchez said above.
While you think Avid is missing features, I think it’s a much better way to work. I hate the way FCP has all those timelines open, too much room for error. Plus, the way Avid works, and Lightworks did when I used it, you put your source in the source monitor and cut in from that. You don’t get a nested section, you get the actual clips that were in the other seq and you know where you’re cutting from. The FCP method makes no sense to me.
It comes down to preference, not Avid being behind the times. Personally I don’t see why Avid it changing things to try to please FCP users because it’s annoying to me. The “smart tool” isn’t so great. I don’t know why locators are now called markers. They’re not markers, they’re locators!
It has to do with what you started on and what you’re used to. To me Avid is so much more streamlined than FCP. I do know someone who likes FCP better who started on Avid but I also know someone for whom the reverse is true. Ultimately you just have to use the one that gets the job done best for you and your needs.
