Ethanol is basically filler, so you will get better performance (though less than you'd expect) on a fuel with no ethanol, which nowadays seems to be 91 octane. :( And by performance, most of what I've experienced is better mpg, not acceleration.

This. Higher octane in a regular engine only has 1 benefit and that is the absence ethanol which yields better fuel efficiency
