VS is slower and slows down more the larger your solution gets. (And what is the point of solutions anyway?)
It's ridiculous how much faster "Find in Files" is.
Lots of things are at least a tiny bit faster - you might only wait a beat in VS, but in VS Code it's done instantly as your fingers go clicky clicky on the keyboard. You feel like a wizard.
I am currently using both VS and VSCode, Code filling the role of Notepad++. (It totally kicks its ass. For starters - No menu-hunting ever!) Yeah Jetbrains IDEs are usually pretty nice, need to get me back a Resharper license.
