Just to be clear you can't buy "advertised" E60. You have to mix 93 and E85 about 60/40 E85/93(ymmv depending on the pumps actual Ethanol content) to get a 60% E content ratio. Also keep in mind, Just because you buy "advertised" E85 at the pump doesn't mean it's actually E85 either. I see it range from E70-E82 around here at different pumps in the summer and E60-E66 in the Winter.

E60 provides about 95% of the power gains of E85. It also provides a little better fuel mileage, easier cold starts, and takes a bit of strain off the fuel system. The latter only matters if you have enough mods that the fuel system is close to it's limits. So that is why I consider it the sweet spot. The caveat is you have to mix it and on a basic bolt-on car it's easier just to fill up whatever the E pump gives you and drive on down the road. I too just ran it straight when I was NA because it was easier. What I said probably pertains more to those who have Forced Induction.

Thanks for the explanation. I think I’m pretty much done with my mods and intend to stay NA, so I’ll likely stay all E85.
