not like my opinion matters much, but I feel that Apple's stuff was great in year 2010. not so much nowadays. I don't know what would be a reason to favor macOS over Linux
That said, I agree with your 2010 estimate of Mac software peaking in 2010. Mac laptop hardware is still better than Linux laptop hardware. As someone who's considering my first Linux laptop, I need to balance the inconveniences of Linux hardware now with the likely fact I can probably use that laptop significantly longer than current Mac. Somebody has to pay for all those convenient Mac support folks.
The funny thing about that is that it's only with the Apple Silicon Macs that's true. The 2016-2020 Intel MacBooks were a garbage fire.
