Fwiw I played around with it a little one summer and my car ran identical times and mph at the drag strip with Shell 91 (90/10) versus 91 ethanol free which cost about .50 more per gallon. I live at a mile high so our octane ratings are lower.
What id be interesting in seeing is the fuel trims with both

Fuel trims will shift. I tested it but it was a long time ago and I have forgotten by how much.

I run whatever premium is at a station easy to get to, and 93 octane. My car is stock, will remain stock...and will never see the track.
It runs fine. Same with the 300C.
