You’re not alone-I’ve noticed the same snappiness after 22H2! It’s a bit unusual since historically, updates felt heavier, not lighter. I suspect Microsoft quietly optimized some background processes or dropped legacy code, especially with how streamlined some animations feel now.
As for bugs, I dodged the worst but did see a couple reports about network printers losing connection. If you rely on those, might be worth double-checking your drivers or having a backup plan, just in case. Otherwise, pretty smooth update for me so far-definitely a pleasant surprise!
