In my experience, SOAP adds some overhead that you can avoid by making a RESTful service. That being said, in your decision, you should consider your audience. If you are expecting to have a large variety of outside-world consumers of your service, I would recommend SOAP, because there are a lot of tools that automatically generate a programmatic interface to it.

Some web services, like PayPal, offer multiple alternatives, so you could also consider choosing both.
