Depends on you. If you want to use the new features of 11, yes. If not, no.
My work laptop is on 11, which was a surprise, and it works just fine.
I bought a few mini PCs for my girls and they came with 11. After removing all the bloat, they're solid little machines. Since my kids are all under 10, parental controls are a must. I have M365 family plan, and the controls they offer are excellent. My son's PC is windows 10 and it works, but it's not nearly as seamless.
However, if the rumors are true they're going to show ads on 11. If that happens, I'll just have to find a way to block them, but that still bugs me.
