Personally I have been using all 4 terminals, right now kitty fits my workflow the best, but things can change. Guess that all depends on if you need the function or not. Solved: I have a MAc book air with OS x 10.7.5, I bought the adapter usb to serial port.

Alacritty is supposed to work well with tmux because after all that's what it's designed for, but it lacks some capability in tmux as summarised in the table. It is available for download on Windows VPS, macOS VPS, and Linux-based Buy windows VPS. Kitty is also fast, but is not included in that benchmarking link. MacWise terminal emulation for Mac OSX - Best telnet, ssh & serial for Wyse 50, Wyse 60, Wyse 370, ADDS Viewpoint, Televideo 925, DEC VT100, VT220 and Prism. With GPU acceleration on, iTerm2's latency improves a lot, but you have to turn off font ligature, which is listed in my table. With GPU acceleration off, iTerm2's latency is so bad from my experience, similar to the benchmark.

So in the link you provided, I'm not sure if the author opened GPU acceleration in iTerm2. Many knowledgeable people has done the latency benchmarking, that's why I stated I only compared the listed capabilities, which is minor but not much summarised so far.

Thank you for the link! Yes that's what matters the most.
