Plenty of people are having a variety of experiences. Hard to tell what it will be like for you. Ultimately you'd have to make a call based on how happy you are with what you have now, if there's anything in iOS 11 that you might need or want (even if it might simply be security updates), and anything else of that sort.I have iOS 10.3.3 on my 7 it's worthing to upgrade to this version ?
