Some of the international Hyatt properties are very interesting and appealing from a Chicago architecture standpoint, but I lived in the same neighborhood as one of the Pritzker heirs and simply can't spend any money with Hyatt. When you see the consequences, I really mean it.
I have been trying some smaller chains in California recently, Ayer and Sonesta and having some nice experiences. Hilton properties out west will often allow you to select a much better location than the other chains, but it's no guarantee, there are many franchisers.
I've been trying one of the newer Hilton brands in Asia for low cost transit hotels, and the franchiser in this case is probably the best small hotel operator in the world. I'm running up a bunch of Hilton points recently, and mostly inadvertently, though I'm having a really fine time in some of the luxury Accor properties.
I noticed this week that that Vietnam Airlines is running status matching promotions for most of the major hotel programs. On Skyteam I'm already spread thinly across 5 programs, so getting a basic upgrade on Vietnam Airlines might be nice as I consider switching back to Delta for domestic travel.
