I'm normally on about 1 year delay on upgrading macOS for a multitude of reasons. I might not wait the full year but something else will have to force me to upgrade within the first few months. I'd heard from people who were running the betas that it's not ready and they are surprised Tahoe wasn't delayed. No way I'm upgrading any time soon to Apple's least cared for OS with a change this big (and this untested).
I'll be honest, I hear this every single time. But I've never delayed upgrading, and I've never regretted it. That's not to say every upgrade has been a strict improvement, but going back to my first Mac at 10.4 (Tiger) I've never wished I had stayed on an older version. We'll see how I feel after going to Tahoe, maybe this will be the one that breaks the trend. Windows, on the other hand…
There aren't always huge issues or huge time sinks but I'm happy to let other people be on the bleeding edge and I'll upgrade once the Github issues, blog posts, etc have been created/fixed so that when I upgrade I can easily find solutions to any remaining issues I might run into. Especially with Tahoe, I've heard that some apps are just broken, period, unless the developer makes (sometimes significant) changes to get the same functionality working again (that was working fine in Sequoia).
