I have actually had problems with Origin. I don't like a lot of EA's practises, and I enjoy a lot of their games, but I think Origin is a crappy client.
I honestly never have. I've had awesome experience with their customer service also, but have also heard pretty bad stories.
The only time I had problems was when I was redeeming codes from the Humble Origin Bundle. Which is understandable, because *everyone* was redeeming codes. Comparatively, when Steam gets overloaded from use, the whole site and sometimes the client goes down.
The three times I've used EA customer service were good experiences as well.
"There must be some kind of way out of here, said the joker to the thief. There's too much confusion, I can't get no relief."
