That's true, I can't complain with 46mpg without trying for fuel econ, so unless you're above 100 a lot I doubt there's a huge difference.
That being said I don't think anyone is arguing there's a reason for necked versus faired, I'm just saying I don't find them all ugly, the Ducati Diavel on the other hand and several other naked bikes I'm not a huge fan of so I can see where people are coming from.
I probably feel the same about the faired sv650/1000 that people feel towards the naked version
