Same experience here. Super impressed with the speed and the advanced flows. I did not do a backup restore from my old to new homey as I thought it might be a good idea to revamp my flows and design. So I took the weekend to add the devices and have my “old” flows on one side of the screen whilst I familiarized myself with Advanced flows and converted them into a (way more efficient) great working new built.
All in all very happy with the new homey (yes there are still issues/missing cards etc), it’s aesthetics and performance
