One representative comment that someone made to me at a conference was along the lines of "Since my boss encouraged us to move to Emacs, I've never spent so long fiddling with and arguing about my editor config. After a while most of us moved to Cursive and all that just went away".
I think Emacs is generally easier to get along with these days, but it'll never be as easy to use as a "normal" app where things just work out of the box. Some people like that, and others don't, but it's not as simple as a division between newbies and experienced users. They're roughly equivalent in power these days, some things Emacs does better and others Cursive does better - fortunately there's plenty of room for both, even in a userbase as small as Clojure's.
