Honestly I think they are all awful, just cheap crap. I had never heard of PTR before Hilton and I am amazed that anyone would go out and buy that stuff based on the Hilton experience. The shampoo leaves hair so dry, the conditioner is useless as well as being too small, the shower gel again, leaves the skin dry. I know of no woman that would touch that stuff, so I'm forced to think its for baldies. It strips the hair of every last nutrient and moisturises not one bit. The hand lotion is such a joke, many of the girls I know who work in the hotels complain how terrible it is. It leaves your hands in dried bits and lets remember its supposed to be for "the body". All can pretty much be said for Crabtree but it smells better. The worst part of C&E is the poor bottle design in trying to get the liquid out, they are not as squeezable as PTR.
The Waldorf Ferragamo stuff is passable but not brilliant. The bath liquid is OK.
The only one I have found to be decent is Rituals which is available at a few hotels, typically in suites. Schiphol Hilton comes to mind.
