Big Sur seems decent. I’m interested to see how the ARM transition pins out.
However; we can’t ignore the butterfly keyboard debacle; a number of unstable iOS versions; the ludicrously-priced $6000 Mac Pro, (those wheels...) - and a very un-generous axing of 32-bit support with Catalina.
I absolutely refuse to upgrade on my personal MacBook beyond Mojave as I have legacy audio plugins that are 32-bit I’ve paid for that do not have upgrades I use as daily drivers. However I’m an iOS developer for a living; so my work computer must be up to date.
The road with Apple has always had its ups and downs. I think; for Mac users especially, the decrease in cost/lower price point that ARM should provide will determine quite a bit of the future of growth of MacOS in the amount of market share.
