Adidas running shoes beat the pants off of Nike's, if we're looking only at these brands. UA's shoes (and cleats) are so bad they shouldn't even be mentioned. All of them pale to other specialized shoes. In regular sneakers, if you're looking for quality and not "style", Adidas is about the only company that makes anything with a normal toe box and decent materials. I know what I'm talking about here, as I've got foot problems and specific exercise needs and have put a lot of time (and pairs of Nike and Adidas shoes) into it.
Most of Adidas' exercise shirts fit and hold up better than anything Nike puts out. DriFit stuff was great before but is really turning into smelly, thin, Chinese polyester garbage. The Nike regular " "cotton" stuff is also way inconsistent on sizes, whereas I can usually count on Adidas to always run just a touch big.
The only place Nike really wins is in field uniforms, but they have mailed it in a lot in places like the USMNT, and let's not forget their MLB fiasco. Nike was already big but has gotten way too much bigger way too fast to actually have quality across much of what they put out to us regular people- they're essentially a licensing company more than anything at this point. Which is why I made my first post in this thread.
