Personally for me, I prefer clean, simple sites. White, and off grey is the new black. My two favourite sites have to be Apple an Dazed Digital. Love or hate Macs you can't deny that Apple have the eye for timeless design, it's simple yet effective, and very clutter free. It makes it easier to navigate the site and also doesn't make you blind.
On the same note Dazed is simple and classly like Apple, but it has an edge to to it, it feels much more exciting and...youthful. Normally you wouldn't think having a site that all in black would be all that attractive, but the use of simple tables and little splashes of colour really give Dazed the upper hand. Not only does it look stunning it's also much easier to use. It's not laden down with text, opting instead to use classic black and white images.
Of course there are negatives to having that many images, or using too many flash scripts, but who cares, who still uses DSL nowadays anyway?!
