So, I used Vim for years - but frankly I only used what I needed. I never played vim-golf extensively, so please don't take what I say as the reasons I enjoy Kakoune as evidence of shortcomings in Vim. With that said:
Kakoune's multi-cursor support sort of blew my mind when I first started using it. Combined with the always selection first model of Kakoune, it means you can plop down 10 cursors, navigate around, select, reduce and etc all of them separately will actively viewing what they have selected. Finally when you get all the selections you want, you can act on them. That's really my main workflow that I just have to have.
Plugins may perhaps solve my issue. We'll see. I also am not sure how realistic living entirely in visual mode in Vim is. I'm not too well versed in visual mode, so I can't speak on it too much.
Kakoune has really been a joy for me. I just want more advanced features that Terminals can't provide (multi fonts, more UI elements, etc)
