vim overhyped as an editor? It might be overhyped as a programming tool (you won't write 2x the same amount of lines in a day; you will not be 5x more productive), but as an editor, it deserves every single bit of hype that it has.
No other editor stands next to vim. A lot of people dislike editors. It's fine. There are a million tools out there that help people become more productive programmers. You might enjoy IntelliJ or you might not. You might like cscope or hate it. Tt doesn't matter. One needs to find the tools that helps him in their day to day job. But if you need an editor, vim is no doubt the single best out there.
I've switched from vim to kakoune some time ago. vim does have the advantage of a bigger ecosystem, but I do believe it is possible to have an editor better than it.
I've taken a look at kakoune. It's very similar to vim, isn't it? When I say vim, I also mean neovim, which currently is already superior to vim in a lot of ways.
The author of kakoune initially intended to rewrite vim from scratch, so there is definitely a similarity. A big difference is that kakoune operates in terms of selections rather than motions, with built-in support for things like multiple cursors as well. I find it more intuitive to use than vim, and just as powerful.
