macOS has been very conservative in redesigning the user experience; it's aging slowly like fine wine. There are a few hiccups occasionally but I feel it's a lot more polished and elegant compared to the quirkiness of earlier versions. I don't get this common sentiment that it was better in Snow Leopard etc.
Stability is great, power consumption is awesome since the introduction of the M-series chips and I can still do everything (and more) that I did on my mac 20 years ago. Yes there are some more hoops here and there but overall you have to keep in mind that macOS never fell into the quagmire Windows did with bloatware, malware and all the viruses (although I think the situation is much better today).
macOS has been walking a fine balance between lockdown and freedom, there is no reason to be alarmist about it and there are still projects like OpenCore Legacy Patcher that prove you can still hack macOS plenty to make it work on older macs.
We're eating good as mac users in 2025, I don't buy the slippery slope fallacy.
