Either one should give years/miles of trouble free service unless you're riding in very extreme conditions.
I would forget the UN 26 and step up to a UN 55 for a few more $$
Unfortunately, UN55 isn’t available here. Also, I’ve only found SM-BB52 Hollowtech, so my choices are limited.
I don’t ride extreme, but I guess my weight still makes it kinda “extreme-y”, so to speak...
