I like Eurogamer because they're not afraid to bite the biscuit and their writing style has that witty British edge to it that I remember from the likes of NGC. Also it's good to support them because they're pretty much local to me (Brighton). They report on some stuff I just don't see on the big US sites. Kotaku's good for that as well, no idea where they're based though.
My favourite sites with a UK flavour are CVG.co.uk and Spong.com. My number 1 site is N4G.com a news aggregate site. Some bias blog rants, but also the top news there. Kotaku.com (I think) is the no 1 visited game site. Blog format. A couple of the writers are overly inflated with their own pompousness. PSU.com ,for PlayStation, s the biggest independent site ive seen. But not really any exclusives. MCVuk.com for business analysis, and Gamasutura.com for occasionally deeper articles.
EDIT: let me add gametrailers.com Bonusround weekly show is a superior talking heads programme + Zero Punctuation humorous but informative videos + my new favourite the HipHopGamer. At first I thought the guy was doing a spoof act, but he is genuine with a real love for video games. Not everybody will like what he does but i think it is great stuff.
