Westin is generally one of my preferred brands - however, it is also very inconsistent. Bed quality differs greatly as many properties seem to have gotten rid of the pillow toppers and thick comforters that make Heavenly Beds so heavenly. Of course, some of them are still amazing (including my latest Westin stay at the Moana Surfrider).
To those in my personal life, Westin is definitely seen as higher quality than other brands (one might say "bougie".) There are some Westins with really great designs - the Westin Galleria Dallas sticks out in that regard with the timeless wooden built-ins and window seat (for some reason, it reminds me of Frasier's Seattle apartment).
