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

OK, after 150 miles using non-ethanol gas, I've determined my car likes non-ethanol much better! I'm glad its available here, didn't see any in Virginia.

The biggest change is on starting. The motor now fires almost immediately!! It's really amazing how much difference there is on initial start up. It costs more but since I don't drive it everyday, I can swing it.

It still take some cranking on hot starts. I just open the throttle as its cranking and it starts. Need to try a spacer on the carb, I guess.
