Well, it's been my experience that EA responds much faster to customer service inquiries than Valve does, but rarely are their "solutions" helpful. So it's really a tie for last place to me.
I have never been able to successfully log back in to my Origin account after logging out without resetting my password multiple times before it actually works. I can change the password to the exact same thing 4 times, but on the 5th time it will actually let me in. Frustrating, but I don't often use Origin so I don't worry about it too much.
