Is flex fuel good or bad?

Flex fuel gas mileage tends to be somewhat less than standard gasoline mileage. However, since ethanol has at best, an 85 percent energy density, when compared to gasoline , you can see that ethanol does not get better gas mileage. Raising the octane level may increase mileage a bit, but not enough to notice.
