Gamespot is better because of the pros and cons section. I find IGN is too generous with mainstream titles but way too harsh with less known titles (for example, they gave Phoenix Wright a 7.7, it is one of the best games on DS, Gamespot gave it an 8.8; 8.8 on Gamespot means better things than 8.8 on IGN. IGN essentially has a checklist of things, if the game doesn't satisfy that checklist then they score it lower even if it is fantastic. IGN doesn't rate games on how fun they are, Gamespot does.
Either way, I am not fond of either site.
In terms of which site is more popular (amount of visitors) IGN is the top site in the US, but Gamespot is, and has always been, by far the top site worldwide. This is according to alexa.com
I describe myself as a little dose of toxic masculinity.
