Kitty is super fast. Very stable. Well maintained. Provide the minimal features (split screen, tabs) for a fully working terminal (no need to add another indirection layer, like tmux, that will add complexity to your workflow, or hope that your OS have a window manager that will fill the features gap left by Alacritty).

I understand the point of Alacritty, their reasons, and it is a great terminal but it seems that Kitty has all of Alacritty's strenghts plus do not lack the minimal set of features to make it a fully working terminal out-of-the-box.
