I don't load either, but if I may offer an anecdote:
I speak fairly often with Randy and Coni Brooks. Both tel me that they are very often driven by customer demand more than actual need or even benefit.
Boattails and poly tips are good examples. Randy told me a couple years ago that he'd never have offered bullets with boattail bases if customers hadn't constantly demanded them. They are more expensive to make, require separate tooling, add yet more inventory demands, and (says Randy) add little if anything to performance. Worse, they make an already very long bullet even longer.
Poly tips drew almost the exact same comments from both Randy and Coni at the last SHOT Show when I managed to buttonhole them for a few minutes.
