I think they can be compared because they compete for the same type of user, and if that user is doing this as part of their business then dropping $ on a tool that's a 9/10 instead of a 3/10 is going to be worth it.

I want to see kdenlive overtake everything, but it's simply not there and given its progress over the years (I've been following pretty much every open source and closed source screencast oriented video editor for years) I don't see it ever getting there.
