I would say I visit gamrConnect the most, followed by gamrFeed, then gamrReview, and finally VGChartz.
Yes, I work for Feed and Review, but I really only go on the former when I'm posting news, or perhaps once every couple of days, and Review doesn't update particularly often, but I make a point to go and read all of the recent reviews every once in a while.
Just so you know, the "official" Quantcast statistic is that, in terms of unique hits, Feed >> Connect >> Review > VGC.
In terms of overall hits, it's Connect > Feed > Review > VGC
