It's very powerful. It's great for making desktop apps too if you're more used to using html and css for UI (if you use the Hybrid version - the standard uses XML exactly like Xamarin I believe). The only downfall it has at the moment is that it should also allow web deployment as a webapp too then it could be a true one and done framework.

You can get around it a bit by putting the pages into a library instead and have both a MAUI project and a Web so project that uses the same pages, just with different setups.
