Be definition, 'naysayers'are saying a given choice is bad. Similarly, you phrased it as 'choose to avoid it' vs 'would select another option', which isn't the same thing in terms of decision making. I *avoid* pizza with pineapple on it. I *preferentially select* pizza with pepperoni over pizza with sausage. I am naysayer for pineapple pizza, but if a buffet doesn't have pepperoni I will just take sausage instead.
Do as you will. For me, that's simply one piece of information. What is their selection criteria? In other words, do the mechanics value the same things I do? I don't really care if the 5.0 is easier to work on or that it will make more power than the 3.5EB if you add a supercharger to the Coyote, so those mechanics who chose the 5.0 citing those reasons are irrelevant to me. I similarly don't care about fuel economy, and the cost of the option to upgrade to the 3.5 is negligible to me, so also selection criteria that are valuable to some but not to me. Similarly, they seem to be irrelevant to the OP. Trying to convince him he made the wrong choice based on 'random mechanic polling' accomplishes...what?
