Absolutely the pure gas is the better choice, even at a slightly lower octane.

I can get non-ethanol 91 locally but have a hard time finding it away from home. If it was readily available everywhere I'd do it. Since its not I just go with the 93 octane and an additive at every fill up. I just don't like the idea of switching back and forth (no reason why and it probably doesn't hurt anything, I just don't do it).

To your question..I would definately go with the highest grade of pure gas I could find as long as the bike runs well on that fuel. As mentioned, the alcohol contributes to the octane %, so it's cheaper all the way around (profit margins are higher) for the vendor.
Pure gas is much better for several reasons, some of which are: pure gas lasts much longer before oxidation sets in, ethanol is hygroscopic, ethanol is hard on seals and gaskets, ethanol is very hard on fuel tank linings and especially non-metallic fuel tanks, you will get less fuel economy with an ethanol mix (varies with the actual percentage of ethanol).
Energy policy in this country and Europe is very confused. Mandates to create a targeted % of energy utilizing renewable fuels has many, many unintended (and in some cases intended) consequences. The ethanol mix in gasoline seems to be more political than it is energy-saving.

don't think the brand makes much difference , I do work at a refinery around here and you see all brands of trucks fill up there , shell , Mobil , speedway or independent , they all get it from the same hose , no ethanol free here that I have seen

Me too - I run non-eth anytime I can, even if it costs more. My bike runs better and gets better mileage (mathematically verified. Plus I have no ethanol storage issues.
The only negative aspect is the additional cost. You will never recover the difference in cost with the additional mileage of non-eth.
One has to also keep in mind that ethanol blended fuel costs less because it is subsidized with our tax dollars. If it wasn't it would cost more than non-eth.
