I hear and read this kind of comment a lot about a lot of expensive products and I find it a false rationalization. It's basically saying IF you can afford A THEN if you must buy only the expensive genuine accessory ELSE you are stretching yourself too thin. That is a nonsensical test. Except for maybe mega-multi-millionaires and up, a lot of people with decent disposable income understand it's neither unlimited nor guaranteed for life and that whatever $ can be saved buying cheaper substitutes is $ that can later be put to more satisfying uses.
On Apple products, sometimes the accessories are worth buying over 3rd parties -- the Magic Trackpad, for example. But when it comes to Apple Watch, the bands are expensive for what they are. I'm very happy with the $10-20 knock-offs on Amazon and eBay. The one I'm currently wearing is 3 years old and still has the grip of a gorilla. The differences between real and fake are minor for the sport loop types I wear, and, even if the fakes didn't last as long, they are exponentially less expensive so I could buy a replacement and still be ahead. (I would also add that the quality of knock-offs had much improved since Series 0, which is the 2015-16 timeframe you stopped buying 3rd party bands).
Then we get to the AWU bands. $100. I had to do a double take the first time I saw that. It's the same material that Apple uses in it's overpriced $50 bands. Zero way for Apple to justify that steep of a price hike. Apple just ginned up the price because they want everything AWU to seem "ultra" premium. It's a common marketing tactic to make people believe something that is actually average is higher quality than it actually is.
So thumbs up to those, like yourself, who prefer the genuine Apple bands. You gotta do what makes you happy and satisfied. But it doesn't mean that those who reject Apple's bands and buy the 3rd party instead can't actually afford the Apple bands or are financially stretched. Its just that we find them a waste of money -- money we have, but are not ready to let go of for something that wouldn't bring us anymore joy over the 3rd party ones.
