Dunno if that makes Ghostty "better" than other terminals, probably not. It just ticks the boxes of ligatures, fast, integration with wayland, simple amount of configuration to work how I want. It also seemed to have a focus on "correctness" which I appreciate. I don't use any of the tab/ssh/whatever features. I know ligatures are the new vi-vs-emacs religious war. Without that single feature-request, I'd probably just use foot. Swapping terminal also isn't that hard, it'd easily swap to something else if it gave me a reason.
I do think its reasonable to question focus on a millionaires toy with a large social presence vs other projects, helped by the somewhat --if not intentional, at least side-effecting -- hype-focused release style of Ghostty. Would it be nearly as successful if it were released anonymously at a 1.0? Probably not? Maybe? It does score highly in sort of arbitrary feature & performance benchmarks so it would probably still have a number of users without the name attached.
