Multiple. Don't visit a single site exclusively.
I routinely check IGN, Destructoid, and Siliconera. IGN has pretty extensive coverage and gets a lot of exclusive stories, but they tend to present everything in a positive light and rarely seriously critique games. I find most of their reviewers incapable of true analysis of game design. Destructoid articles are heavily biased, but that's why they're useful. You don't just get news, you get an opinion. But they also have their bad eggs. Siliconera is sort of the opposite of that -- for the most part, they present the news, uncontaminated by opninions. Their greatest strength is also their weakness: Siliconera almost exclusively covers the Japanese side of the industry. Their coverage of gaming is extremely limited because of this, but there is very little overlap between the stories you'll find there and the ones you'll find on other sites. One of my biggest pet peeves with IGN is their reluctance to post news about games that haven't been outright confirmed for release in America -- and, sometimes, even about Japanese games that are definitely coming West. DToid is somewhere in the middle.
