I've been running the RC and I have had no issues. Some of the design choices (sidebars particularly) are strange, but it's generally fine.

I recommend not overcomplicating your life and just staying on the latest macOS.

It took a day of getting used to it, but I have had no issues either. Some of the commentary on this thread seems overly critical to me, but you tend to see that on any Apple thread on HN. There’s stuff I like, some stuff I don’t, but in the end I’ll adapt.

I think sime people just hate change. I am convinced that some folks complaining here will be complaining when MacOS 28 comes out and changes some OS 26 feature they have grown to like.
