Seems the pitch is just that it supports Apple specific bells and whistles like the emoji bar and beyond that has the stuff other terminals have. I use tilda and use that because it has a critical core feature I haven't seen in other terminals: it appears full screen over all other windows with a keypress and disappears the same way. Since I use terminal heavily I don't want to treat it as just another window but as a first class experience which tilda allows. I don't really get why you'd make yet another terminal without some fundamental core functionality difference like that.
