IOS 11 to iPhone 6s?

Should I update my iPhone 6s to IOS 11? I had a previous iPhone and when I upgraded, it slowed down.
iPhone 6s users, what are your experiences?

I have an iPhone 6 with iOS11, and it has slowed down a tiny bit, but as you have a 6s with a faster processor that shouldn't be a problem on your iPhone.

But I strongly suggest that you wait for iOS 11.02 as the present release is frustratingly buggy. For the first time in over 5 years of iPhone use I'm getting the kind of problems which made me leave BlackBerry, Android and Windows Mobile behind. I've had to reboot my phone 3 times today already and it's still not 10am where I live.

The camera has had faults, the text keyboard frequently fails to appear when a text box needs filling, and this morning the phone totally lost its data connection and I had to go to Settings>General>Reset>Reset Network Settings to get it working again. Those are just a few of the problems, there have been many others. IOS 11 is also annoyingly unintuitive with some of the new features.

I've NEVER seen so many bugs on any iOS release before, it's more like running a Beta software version.
