I'm not trying to convince you to switch at all. Choice of editors is just a matter of personal preference.

I'm just pointing out that all the features you've listed as lacking in Vim are built-in, widely used, and documented. And of course, these features can be used at the same time, there's nothing preventing you from doing so.

I didn't realize that git support (changed files/diffs) was built-in. I'll have to research that.

Git support, as opposed to getting a list of unsaved files, would be better served by installing vim-fugitive.
