All terminals have latency, but that doesn't mean that all terminals have equal latency. Point was that anecdotes about subjective instantaneity are pretty meaningless, especially without any reference point.

It would be much more meaningful to substantiate the discussion with actual data; the measurements done by danluu are one example https://danluu.com/term-latency/

Of course there can be quibbles about the specific methodology, but its still much better than having no data at all. Especially for something that is as measurable as latency is.

In general if you claim something is fast, back that claim up with some numbers.

Some applications using OpenGL or Vulkan and Wayland compositing end up with latency related to one or two frames of the screen refresh. Which means that characters appear onscreen much faster on a 144 or 240 Hz display.

Not really a surprise but something to be aware of.
