Another area where "Better" is worse, is in appliances. Lots of the wealthier people in my area like to remodel their kitchens with trendy, expensive stainless steel appliances. Like SubZero for refrigerators and Wolf, Thermador and Viking for stoves. Or obscure European brands. Unfortunately, they have horrible reliability (and safety) issues and parts are hard to get and expensive. They would have been better served with a cheaper, reliable, but boring Whirlpool appliance. Its especially hilarious when they have all this fancy stuff, but can barely cook. I know a woman who spent many tens of thousands remodeling her kitchen with the latest and greatest and most expensive stuff around, but some of her close friends told me she can't even cook. Sure enough, one day she opens the fridge to get me a soda and its practically empty except for some sodas, condiments and bologna! Its all about the image.
When I remodelled my kitchen over the road in my old house, I went with what the kitchen company recommended for the dishwasher, stove top and oven and I was reasonably happy with my choice.
When Bilby and I remodelled the kitchen here two years later, we went with better appliances that suited OUR needs. Such as a 900mm cooktop, a Bosch fan forced oven and a Bosch dishwasher. They cost a bit more, but I have a lovely wide cooktop, which is great with big pans, and a kitchen I can cook in. I also have granite benchtops and a glass splash back. Quality, but functional.
With regards to your post though, I agree, some people go for the 'fashion' and 'image' and not for what is best.
