Like:

. _amazing_ integration with Julia. The only reason why I used Jupyter notebooks was for the concept of cells. But VS Code does that better AND the code is valid Julia code (as opposed to when using a Jupyter notebook, where the thing generated is not valid Julia code). Same goes for python.

. I LOVE the "Remote SSH" extension. With zero effort, other than installing the extension on my local, I can run VS Code backend on a remote machine. This allows me to, again with zero effort, be able to work on a machine that might not be great (like my laptop) but point the backend to some big machine and do some serious data crunching with a frontend on my laptop.

. I really like the CTRL-SHIFT-P box (it's called the "command palette"). It's the ability to _search_ IDE commands/features from a search box. This is in contast to having to memorize a hotkey (like vim) or clicking around various dropdowns (like Microsoft-inspired stuff).

. Like it's not vim-fast, but the UI is still quite fast.

. You CAN customize, but on the other hand all defaults are quite good.

I've been a huge vim fan for a long as I can remember, but VS code has replaced it for all my coding. The only situation where I still use vim is if I need to open multi-Gb data/log files.

EDIT: As other people mention PyCharm - are you nuts? PyCharm is VERY sluggish. I hate it.
