I'm not sure i follow... a terminal emulator is a display. it is basically only there to visualize your shell (i.e. bash, zsh, fish, etc).
From this sentence alone it sounds more like MobaXTerm or RoyalTS than a terminal. Which is fine, but shouldn't be called a terminal emulator, as thats not what it is.
> If you concerned Alacritty, you will see it also compared to rxvt, because rxvt is one of the most fast terminals.
thats a very feeble argument. Alacritty is - to my knowledge - the only terminal emulator with GPU Acceleration. So yeah, if you don't have a good dedicated graphics card, you won't really get any performance improvements over the usual terminal editors which only utilize the CPU... but its just plain wrong to equate their performance.
> What differentiates this from Microsoft’s new terminal? Features are listed, like coloring, folding.
i'm not sure i follow here either... the coloring is set by the shell - the emulator just displays the colors. and windows terminal does support colours
and folding doesnt really look like something i'd ever want to use...
