VS Code with vim keybindings is extremely popular. If you don't know how to use vim, you just don't realize how much of a time/effort saver it is. I can't imagine not having wrist pain if I had to use the mouse every time I wanted to move my cursor around for more than a few characters/lines. Trying to not use vim feels like going back to the stone age whenever I can't use it. I like to use vim bindings even when I'm editing english.
I used vim for 5 years, afterwards I switched over to Emacs, and I couldn't disagree with you more. What's clumsy and slow is having to switch between insert mode, normal mode, and visual mode hundreds of times while working rather than just using modifier keys for special actions.
If you're entering normal mode for one or two commands at a time, that could be problem. However, if you're fast at entering normal (i.e. use jj, fd, Caps Lock as Esc, etc.), that's not a meaningful overhead.
On the other hand, having to constantly hold Control/Alt, including long chords (e.g. with prefix + count), feels much worse for me. I use Emacs keybinds on the terminal (outside of vim), but I can't imagine having to constantly press modifiers. It's not as comfortable as switching to a mode where those actions are explictly first-class.
i think what you're describing sounds a bit like visual mode which is just v
d and p for cut and paste if moving stuff around needs to be done (dd for whole line, 5dd for 5 lines, v and then j a few times in visual mode before d or y for yank (copy), etc...)
Note how you don't have to strain your pinky to hit ctrl for any of these?
