Yes... it runs A LOT better, when comparing the same octane levels.
From what I'm told, they introduced e10 because they needed to add ethanol to the gas to get the octane levels back up from adding detergents and other non performance additives. Since the additives lowered the octane rating and ethanol has a high octane rating (which is why everyone likes to run it), it boosted the octane levels back up fairly inexpensively.
Which gave ethanol a bad rep because everyone noticed that stuff ran worse with e10 gas, compared to ethanol free gas, and people automatically assume it's the ethanol
