iTerm2 is still the best terminal emulator on macOS, thanks to the hard work by @gnachman. I've tried to switch to alternatives like Kitty and WezTerm several times in the past decade, but none of them beat iTerm2 in terms of stability, feature richness, and ease of configuration. While iTerm2 may fall short in rendering efficiency, compared to how well it performs in other aspects, that's a minor concern.
