A long time ago I switched to Emacs(with evil mode) from whatever IDEs I was using but it was also way too slow. I then switched to vim and configured it with lots of plugins. This was the best thing ever. I transitioned to Neovim but Vim would also be OK.

Vim/Neovim are always fast. Even with 30+ plugins configured. I can run them on any hardware and they are blazing fast. Not to mention the superiority of modal editing if you are used to it. I have every feature I need (LSP/code completion/diagnostics/even debugging via DAP).

Pretty sure that I won't switch setup for a long time/ever again.

https://spacevim.org/ is also good alternative , it is basically vim/neovim sensible plugins pre-configured with smaller config file and simpler management.

There are many of these distributions and I recommend them to people new to Vim because they can get a good out-of-the-box experience.

However after some time you probably want to configure your own and only include what you truly need. For this a good solution is to just adapt https://github.com/LunarVim/nvim-basic-ide to your liking. This is made by the author(s) of LunarVim.
