"....KA is very consistent in protein level and overall quality"
KA is consistent year to year, and in my experience, literally across the country.
Wally World typically sells KA for less than anyone else.
I have tried multiple unbleached/all purpose/bread/organic/non-organi flours, and every single one has differences in the amount of hydration needed to reach the same consistency, and none has exceeded KA in rise or oven spring (quality of the crumb). I haven't found a flour I like better than KA. I try new flours out now (Costco had an seasonal special organic, hard wheat all purpose flour that was "local", and priced out sig less than KA)...it was ok, but didn't have the rise or spring of KA. I have mixed the remaining flour with KA, and the result is good, but I doubt i'll buy it again. It would be noce to find a locally milled flour that is as good or better than KA, buit I haven't found it yet.
