Neither,
While not an avid PC gamer anymore, pretty much all of my PC purchases are on steam. I don't get why people get up in arms about competition, it is good for the consumer.
I've brought it up before, but without Microsoft's heavy risk/investment in LIVE, you would not have PSN in anything near it's current form.
Like Steam "enthusiasts", Sega/Sony/Nintendo "enthusiasts" were deadset against microsoft from entering the console race and today online/social integration in games is the norm.
Same deal here, Original will probably go down in flames..but maybe they won't and we will all gain from it.
