In other words you really should just test it out. Run a couple of tanks of each and compare.
There is less energy in ethanol and the computer cannot adjust for that.
So, you guys have both tried it for yourselves, compared a couple of tanks of E-10 and a couple of tanks with no Ethanol? I have. There is virtually no difference.

And if you don't believe the computer can make the adjustments, you have not kept up with modern auto technology.
