Im trying to figure out how you were convinced otherwise, but I would rely on empirical real world results...

This is the video of the failed Dremel test:
The outsole rubber is 2.2mm thick and the short abrasion lab test resulted in a disconcerting loss of 2.1mm of rubber material. The damage is so extensive that the underlying EVA foam is actually exposed:
The lining in the upper in high friction areas such as the heel also failed the Dremel testing:
Runrepeat gave the Prima its lowest rating for upper durability, 1/5:
High quality shoes manufactured with better materials will pass these tests. For outsole durability I suggest filtering for shoe models that have at least a 2:1 ratio of pre-Dremel test rubber thickness to post test thickness. For example, the Asics Novablast 5 has an outsole durability ratio of 3.66. The Novablast held up well to the Dremel test, losing just 0.9mm in depth. Asics was also more generous in terms of outsole protection, offering 3.3mm in thickness vs Adidas's 2.2mm for the Prima.
When I shop for shoes I think its important to factor in durability when assessing the value proposition of a shoe at a given price.
My focus has for the most part always been on durability & comfort, which ironically the Asics I wore (Nimbus & the Novablast) did NOT hold up at all compared to the Supernova at all leaving me to ditch Asics completely. I've dealt with concerns of traction from the lack of rubber, abrasion holes from the thin mesh, and a more compressed midsole in half the time I've owned the Supernovas, and very little noticeable wear on the outsole. I was wondering why these shoes haven't really been popular, and it seems that they either have a fit that is just different from what people are expecting, or they've come across these reviews which may not reflect real world experiences. They are absolutely probably the most comfortable runners I've EVER owned, and thats saying a lot. I honestly should buy another pair just because of that sentiment...Thanks for your perspective.
The Dremel outsole test may not completely translate to real world experiences for every runner but it's still useful. I think runners that may have a biomechanical flaw such as a twisting motion at toe off will find such a test more applicable.
Asics shoes always doom me. Just not a good fit and the brand is still too EVA centric. They don't even make the Metaspeed models or the SB in my size. That sort of penny pinching on molds and tooling makes me doubt their commitment to performance footwear or their long-term financial wherewithal to compete with the majors such as Adidas and Nike. Considering the challenging 3 years for athletic footwear, Asics is probably struggling to hang on and maintain R&D investment and athlete sponsorships.
