Is there commonly anything noticable from running a less name brand that anyone has seen/read about or reasons to stay away if possible?

Lately I have been filling up at a Kroger (grocery chain) mostly because their price seems to be on the better end for the city AND for like $.06 more I can go from 89 octane to 93 octane where as everyone else would be typically a $.15 increase for 91.
To be sure, I know our engines recommend premium which i assume they mean 91 octane, but 93 would be better to run than 89, right?

And back to the initial comments, do you think I would notice much difference (positive or negative) if I ran 91 octane from a name brand (Shell/Exxon/Mobile/etc) versus my current 93 from Kroger? Or to take it further, name brand 89 versus Kroger 93?

Im sure more can come into play for people with FI, Im still NA, but id welcome comments pertaining to both sides just to see how its affected if at all.
