just installed ghostty, looks cool. but my honest question is how it is significantly better than iterm2 to justify such a switch? I am aware of the fact that it is faster, uses less memory, various configurations is more straight forward. but is that all?

I have the feeling that I must be missing something big here.

I’ve been using iTerm2 for years. I’ve tried ghostty a few times and quickly went back to iterm each time for various reasons I can’t immediately recall. There is nothing I can think of lacking from iterm.

That said; if I was working more on Linux or Windows where iterm doesn’t exist it looks like ghostty would be a good option.

Same. As far as I can tell, Ghostty is still in active development and unfinished. For regular use iTerm 2 is a complete product that can be relied upon.
