Proton is packed with more functionality than wine (by nature of being a superset fork), and is wrapped in a much simpler box to open than Wine for the most part, so it gets a lot more praise and user adoption. I love wine and have used it for decades, but prefer Proton heavily at this point for games. I'll still use wine for desktop apps though.

I imagine Lepton will eventually be super easy to install and get running compared to Waydroid, which I can also attest was a massive headache.
