I don't think many would say the 300NGs are of a poor ride quality. I was really impressed with them myself. I do think it'll be interesting 5 years down the line, as the Mercedes quality really stands out here. The first GNE batch of Citaros (5275 for example) are still as good as they were on day 1 in service. Of course that proven track record isn't there with the 300NGs yet.

I found an interesting presentation based on Coca Cola using Biomethane vs Diesel as a trial. It was the best comparison I could find on fuel costings too. Here if anyone wants a look.
