Non-ethanol fuel will burn better, and therefore be better for your engine, and it's better for the atmosphere. Burning ethanol produces much more ozone, especially during warmer months, which is why the Clean Air Act currently prohibits the sale of E15 during the summer months. Small amounts of ethanol will exist in your "non-ethanol" fuel anyway because it is used to control the octane rating, but it is much lower amounts than those fuels that carry an "E" rating, such as E10 and E15. The reason that "E" rated fuels were created was because of the push to find "renewable" fuel sources, it was not because ethanol makes an internal combustion engine run better. It does exactly the opposite. It will not burn nearly as efficiently. This is obvious once you realize that ethanol is used as an octane booster. Octane is not an additive used to make fuel "better", it is simply added to inhibit combustion so that only the spark process will cause the fuel to ignite inside the combustion chamber. Anything causing ignition other than the spark is referred to as "detonation", which is very bad because it happens at the wrong point of timing during the combustion cycle. (none of this applies to a diesel engine)
A lot of people make the mistake of thinking that higher octane means better fuel, it does not. High octane fuel is used in high performance and "race engines" only because those engines have very high compression and would be prone to detonation before spark without it.
If you can find "non-ethanol" fuel then use it. Do make sure that the fuel has a high enough octane rating for your engine's compression.
