Can you add a flappy bird demo? I find that flappy bird demos for state-over-wire tech like LiveView and Blazor to be a great gauge for performance and latency. If there is the slightest delay or inconsistency in performance you will be able to tell immediately.
I have a longer list of such technologies here: https://news.ycombinator.com/item?id=19716696
Nice list. I have been cataloging LiveView workalikes (https://github.com/dbohdan/liveviews), and I've added some of the ones you mention.
