Win8 was great once you disabled Metro and went back to the classic start screen. 10 is better but need to disable a lot of the privacy features.
Also for OEM's it's going to take time to catch up with drivers anyway. My Sony Vaio was missing a few drivers for stupid stuff like the card reader etc. Both graphics cards were up to date but Sony has a proprietary software switch on them so I couldn't use any battery saving features until they come to the party.
If you are running 7 and have no urgency to update, just stay where you are for now. Or even image your install, install win10 (tell it to delete files while it updates so you have a fresh install) then image it and go back to win7, that way you can switch between them quickly and not have to worry about the activation period running out on the free win10 upgrade. This is what I did.
