Seconded. I keep hearing about ghostty but I have yet to see a strong enough justification about how it is _that_ better. I use konsole and has significantly more user friendly screen to manage settings. I heard about ghostty's performance so I did some timing tests and ghostty was faster than konsole but not that much - not in any perceptibly significant measurable sense.
I never got the speed thing. Ghostty at least seems slower on my machine compared to foot(client).
I went from Alacritty to Ghostty for ligatures and some other small goodies. I could probably get those same goodies with Kitty, but I didn't want to try nor have the desire to try. I may go back to Alacritty if I grow tired of Ghostty.
