ITerm is native, supports plugins (Python scripting API), is CPU/RAM friendly, with milliseconds input (very important for touch typing), it’s open source (GPL v2), the author is a proficient programmer which I hope to sponsor via GitHub Sponsors program soon although you can already sponsor him via Patreon, offers smooth split panes, hotkey, buffer search, intelligent autocomplete, instant replay, an exaggerated amount of extra options available from the application settings, additional shell integrations, inline images, password manager, annotations, and the list of features continues with the beta builds. There’s a theme that makes it look compact (nicer?)
I use iTerm (unfortunately only available for macOS)
