I turned my roadster into an interstate mostly because of the scarcity of enthanol-free gas stations near me, and I wanted the greater fuel capacity of the interstate tank to make sure I didn't have to fuel up with E-10 fuel. If a person doesn't need the extra fuel capacity, then we're really just talking about which bike is more appealing to the eye...
I have a '70 commando, and I always hated the look of the key in the left side cover. With the exception of the key location, my bike looked great originally as a roadster. Once I began making changes, it didn't look as good until I finished the complete transformation. As I changed each thing one at a time, the bike looked disproportionate in different ways. Now that the transformation is completed, I think the interstate version looks as nice as the roadster.
One of the things that I thought looked great with the early roadsters was the chrome shock covers. When I changed to Koni shocks they disappeared for good unfortunately. I also liked the fenders painted to match the tank and side covers and my bike has been like that for 40 years in both configurations. I'm in good company with that opinion as Matt from CNW also paints his fenders to match, and his bikes are probably the nicest looking nortons around.

Ok, looking at nortribuell's post, I'm tempted to follow suit. Same bike in both of my pictures in roadster, then interstate trim.
Here's the above bike transformed into an interstate.
