It's not "cheaper" because that's just MSRP. Again, MSRP doesn't matter for the retail customer. It's the actual market selling price. I'm not talking about "upgrading" trims. I'm talking about having two vehicles that are comparable in terms of "standard" features.
Also, what do you consider a "no brainer"? Does that mean out of a given 2 options, if one option achieves over 51% acceptance or higher, it's a "no brainer"? I wouldn't consider being a hair over 50% a "no brainer", but maybe you would. For me if 3 out of 4 people make the same choice given the same problem set, I would begin to sense that the common option may be a "no brainer". It would take at least 4 out of every 5 people to convince me that there's a "no brainer" option.
