the problem here is that a bicycle is a "simple machine" which in reality makes it one of the most complex devices to fully understand and implement.
every component part has multiple , interdependant and critical functions, making quantifiable,measureable scrutiny of the benefits of singular properties & effects a nearly impossible task.
vehicle dynamics are affected dramatically with modulating intensity of cornering forces; changing road surface & terrain & aerodynamic interactions; the rider's mobility & fitment affecting weight distribution & transfer and efficiency; a broadly varied,yet very low power application levels and disparate operator skills,physiques,fitness levels & motivations, compounded by their ability & quickness to adapt as well as their sensitivity to the machine and its behaviors.
one just cannot make any sort of all encompassing proclamation of benefits for any specific design or property without assessing that element's affect on the whole in terms of efficiency, handling, cornering, rideability, predictable behavior, reliability, comfort and, as demonstrated all too clearly in this thread, one's aesthetic values, expectations and biases.
