I clicked a total of three times in the demo page before the tab froze and locked up.
MAUI is nice, and I'm glad it's getting decent Linux support now, but I would never use it in the browser.
Avalonia's big money ticket is taking old WPF projects, making minor changes to the XML to load their tools, and instantly making the projects work on macOS/Android/iOS/etc. (for an enterprise fee, of course). Great for forcing internal .NET applications built to run on Windows Vista into the modern world, but I don't think their web platform is a good idea for new projects because of the massive overhead you end up with.
