kitty has lower latency than Alacritty. Alacritty is optimized for throughput and is the best for that, but I don't understand who would prefer throughput over latency in a terminal setting.

I switched from kitty to wezterm. I don't have an official benchmark like the below [1], but low latency is an explicit goal of the project and it seems on par with kitty.
