I think that downplays how much fiddling other tools take. I've never used another similarly powerful editor that didn't require similar amounts of configuration to be useful. And if getting some random plugin working means you have to tweak its code, it's almost certainly going to be fast and easier in Emacs than in the other. With Emacs, you can generally just replace a function after its been loaded. In other things, you may be forking a repo, editing/compiling it, and figuring out how to get the editor to load your version of it.
