Yeah, we also had the same debate on whether we should go with cityscape or first-person street views. I don't think we ever made a final decision, but leaned street view when picking photos.
Our landing page photo changes based on the visitor's IP and host, so most of our effort went into getting the right photos.
On a friendly note, the guy who signed up as no@no.no (seemingly in response to the question "was it worth it?"), probably didn't "no" that.
