If all you know is VS Code it probably feels fine and you should definitely not try Zed - "one of the fastest Electron apps" isn't exactly a ringing endorsement.
I have used both unbearably slow IDEs like Visual Studio, Android Studio, Atmel Studio and very fast and lightweight editors like Notepad++ and Sublime Text.
I don't have any issue with the speed of VS-Code on my machine and it feels the same as Sublime Text used to.
