Off-hand, I've tried 1UP, GameSpot, Backloggery, Listal, IGN, VGRebirth, Gametz, and spreadsheets for keeping track of everything... so far, apart from the occasional feature like this that I'd like to see, VGC has been by far the best of the lot.
I do still keep spreadsheets for keeping track of port differences and stuff, but those are still a bit of a mess. I have a habit of creating files, losing track of them, and creating new ones, only to wind up with like 6 different versions of things. One of these days, I need to sift through it all...
