I like The Mountains' and BHT personally. The Mountain website appears calming/relaxed and seems to be the most personalized/customized for an individual listener.
BHT on the other hand, it looks like they went all out and spent some big dollars on their website. It is a "in-your-face" type of design, with lots of attention to detail.
2 different companies, 2 different stations, 2 different looks, but they both appear good in their own way.
