I think we must take solace from the fact that this platform has gone through months of beta testing, by a similar number of legions, reporting bugs which then get addressed. Apple have the stats and it’s highly unlikely that they released the os before it reached minimum standards.Its not distrust, but rather preference and concern.
Its great that its working well for you, but that doesn't negate the legions of people having compatibility and performance issues. Then there's the UI, and how it gets in the way for some people, making it harder or they just don't like what how it works.
Finally, the idea of fixing something that isn't broken. If Sequoia is working well, no issues, what does Tahoe give you? The major feature of Tahoe is the Glass UI, and if that doesn't interest you, why bother.
The vast majority of users experience are overwhelmingly positive.
When it comes to change, people love to moan don’t they? On iOS at least what’s brilliant is that it completely gets out of your way, minimising things that have no urgent need of being front and centre.
On Mac, not a great deal has changed to be honest. I can still get my work done.
