In some ways perhaps. In most ways not really. There are hundreds of mechanical key switches and many of them feel significantly different from one another. There are indeed bad switches and there are indeed good switches but 99.99% of them fall into the "good category". There's no objectively "best" switch. There are so many types that are good and will last practically forever that its just a matter of personal preference for the way they sound and feel. Some people like quiet switches. Some like clicky. Some like tactility. Some like smoothness. Some people need ergonomic features like split layouts and tilting. Some people prefer standard layouts.
I have some very expensive keyboards (rare vintage stuff and modern custom builds) but in regards to custom boards, once you get over $300-400, you're basically paying for fashion/brand names/artificial scarcity/aesthetic craftsmanship and not utility. Honestly a $60 GMMK with a person's favorite switch (probably around $30-60 more depending on what you want and how big of a layout you use) and a $30-50 set of keycaps will get you 90% of the value that people get out of more expensive brands.
Audiophiles' hobby includes a bunch of stuff that literally has no impact on anything. For some things there's no added value even when taking only aesthetics/superficial stuff into account. There is audiophile hardware that makes a real impact, but there are also people that swear that their absurdly expensive accessory X provides a significant difference when hooking it up to a signal analyzer proves otherwise. With keyboards you are generally either paying for a fashion accessory or an actual discernable difference in the way something feels and which one you are paying for is usually obvious going in.
Both hobbies suffer from diminishing returns that hit hard and fast. You don't have to be a wealthy person to get a great experience from audio or mechanical keyboards.
