There are some issues with time to pull required shipping data with Google Chcekout that may as well play into this decision. I know Google allows a very small window to pull the shipping and there are many times when it goes to the default shipping and not the correct shipping.
I would still rather use Google over paypal any day of the week. I can't stand paypal and or ebay.
