I use Ghostty because it is a native application, and it looks great on macOS and GNOME. WezTerm, Kitty, and Foot don't do that for me. Foot is great though.
After some update, Ghostty stopped working on Gnome+Mesa on older Intel graphics (IvyBridge). It doesn't really feel native to me if it doesn't run everywhere the toolkit it uses runs. I understand the reasons, but it leaves a sour taste.
