I use kitty with i3wm.
I like konsole because of the standard KDE applications feature Alt+Shift+I to search in the application menu (HUD)
Foot + Sway + NixOS =
Alacritty on Arch Linux, foot on postmarketOS. (Both are running Sway.)
I use Alacritty nowadays because the last time I tried Kitty (a few years ago), I had some visual glitches in it and it would launch a tiny bit slower than Alacritty.
I use foot because that’s what was preinstalled with the postmarketOS image for my device, it performs reasonably well, and with a touch screen, I don’t need vi-like keyboard selection (a feature present in Alacritty but not in foot).
