87 ethanol free vs. 93 w/ ethanol?

Recently found a station close to home that has ethanol free gas, but only offers 87 octane. I'm told they will be moving to 90 octane ethanol free in the near future.
Just wondering if ethanol-free might be the better choice despite being lower octane? Or what about adding octane boost to it? I've heard that straight gas burns cleaner/more efficiently & yields better fuel mileage. Not as hard on rubber & plastics, with less residual buildup too.

Run the 93 and don't worry about the ethanol. My 450 has had the same E10 93 Octane in it since October as I haven't been able to ride that much. If it's real cold out, it can sometimes be hard to start, but runs fine otherwise. The ethanol problems are really overstated.
