Only way you get better belts is if you take a lot of time to identify the belt material and size. Experience has taught me to NEVER believe what the guy behind the counter says about their belts, at an auto parts store. Most don’t know the difference between blinker fluid and bacon grease.
Then you’ve never had to warranty your work. I learned a long time ago, I don’t want to do a job twice trying to save a buck or two. My rep means more to me and customers keep coming back.
So you get the parts from the lowest bidder rather than the place with happiest customers. Do you really think NAPA would stay in business selling inferior products? Nuff said, I'm out.
No, 90% of the time I will use OEM belts. Only use aftermarket belts when I’m in a pinch. NAPA sells 90% of its belts for automotive use and wouldn’t survive if it relies of belts used in the small engine world.

So I did the Napa belt crossover for the OEM belts for the OP and all 3 napa belts are slightly the wrong length and 2 are the wrong cut angle
Buy 10 belts of the same brand, width and length. None will be spot on in those critical dimensions. Stretch them out in your hands and see. Gates, Goodyear blah blah blah.
