You've got to read current reviews for properties before going. Conditions are all over the place. It isn't really about the brand anymore.
With that said I've had good experiences with Hampton Inn the past year. Though the maintenance and upkeep is looking a bit scruffier than in the past, I have encountered friendly employees and clean, quiet rooms.
I've had pretty poor experiences with Hilton Garden Inns on service and cleanliness that had 4.5/5 on Trip Advisor but all negative reviews in the past year or so and had I looked more closely I would not have gone to them.
