Which is better - 90 octane no ethanol or 93 octane 10% ethanol

I just moved from Virginia to Georgia and there is a Valero gas station near my house that sells ethanol free gas, but only up to 90 octane.

I was running 93 octane, 10% ethanol in my 273 Commando in Virginia. Seemed to run great, just a little hard hot starting.

I wanted to get your thoughts before my first fill up in Georgia!
