Premium provides VERY slightly more horsepower than regular. For the vast majority of people, you would never know the difference. Stick with regular and save some money. The engine will automatically adjust to either fuel so there is no need for concern in that regard.
Non-ethanol fuel is always better but increasingly hard to find... Since ethanol (alcohol) has less energy than gasoline, ethanol fuels give less performance and poorer mileage...
