Rod, we use both.
Google checkout since inception, I think that was over a year ago. PP, for 7+ years.
I guess it depends what you are looking for. We have every option available, MC, Visa, Discover, Amex. The more options you have, the easier you make it for your customer.
PP has been around a long time, many people are comfortable using them, whereas, Google, as can be seen by this thread, is not well known, yet! Keep in mind that Google will charge
more when they feel that they are well established, this will happen soon IMO.
One more thing, some carts are not compatible with Google, we switched to Volusion and had problems.
