I dunno how much has changed in the last decade, but Avid is an entirely different sort of beast as far as the way it expects you to set up your workflow goes. I find it works great if you’re the initial editor and are working from all the raw footage, but it’s difficult to work with from a fan editing perspective; Premiere and FCP are much more fanedit-friendly IMO.
I haven’t tried DaVinci though, so I can’t offer any advice on that one.
