> VSCode (and all Electron based editors) have undeniable input latency.

Start up time, sure. But VSCode was lauded as the first performant Electron based editor. I just tested VSCode, Zed, and vim and I can't see any difference from when I press a key to when a character shows up on the screen (appears instantly). I'd be curious to see the results of a blind test, and wonder if people's biases against Electron are showing up.
