Matewis: It's slower than I remember, and due to the lack of regional pricing it's often way, way more expensive than steam. And I'm not too nuts about some design choices either, not to mention some persistent issues with the forum. But eh, I don't know, I still like coming here and hanging around in the forums for the occasional friendly exchange (forum does seem far less lively compared to years ago though). That and, I much prefer not having to run a game through a client.
Lack of regional pricing? Being a VPN user, I can tell you that GOG definitely has regional pricing.
