Honestly better in every respect. Very usable (I particularly like the colour coding), and search is now offered as a prominent navigation method (as well it should).
Visually it's nothing particularly special, but who needs things to look special? It looks good and more importantly is much easier to use than the old site.
Now you just need to build some recommendation features into it. I can't speak for anyone else, but there are many times that I've gone to a certain internet retailer, with the intent of only buying a certain product, and come away with loads more stuff due to (good!) recommendations.
