I would put HR up there with Newmar and at the same or a smidgen below County Couch. The specific model needs to be taken into consideration. I feel you get a lot of bang for your buck with the higher end HR diesels.
Every brand had their issues, just need to be informed. I love Country Coaches but dislike the problems with the dry PTO and aluminum radiators.
The HR (and sister ships) s-chassis is a solid foundation with good quality. That being said the remainder of most of the house components are similar regardless of what brand you buy,heating system, ac, etc, as long as you are comparing similar models within the food chain lineup.
