Their options at launch look pretty sad. Lots of major US cities have no offerings, and those that do have offerings are very limited. Zero properties in Vegas? Only 5 hotels in NYC and they're almost all $1000/night looking at Oct 2023. I've checked a bunch of major cities and haven't seen any hotels that are members of chains, so applying elite benefits doesn't appear to be a problem...
I was expecting this to loosely mirror FHR, but it's not even remotely close.
