The odd time I will fill up at Costco first thing on a Saturday morning when the Mrs' SUV tank is nearly empty, but otherwise I refuse to wait 10-15 minutes to save $5 on gas.

I honestly haven't noticed any major performance differences between Esso/Petro Can/Shell/ Superstore/Costco. I've been driving the same old car that requires 91 octane for almost 16 years now. (Toyota/Yamaha 2ZZ-GE https://en.wikipedia.org/wiki/Toyota_ZZ_engine#2ZZ-GE)
The biggest loss will be the use of Esso to keep my wife's Aeroplan active. Certainly didn't meaningfully add to any points balance for me.

As for gas - there is little difference (sometimes none, when all the brands use the same local refinery) in the underlying refined product. It is the additive package that varies (sometimes) including ethanol fraction. Beyond that good luck finding an informed source other than scholarly articles - more myth out on the internet about octane and brand variables than anything.
