Jason Snell, Macworld:

Control Center in iOS 11 is different. Really different. And when you upgrade from iOS 10, it will take some getting used to. But as someone who has been using it for a few months now, let me declare: It’s better. The new Control Center is simultaneously simpler and more powerful. And best of all, you can customize it to do what you want —— and hide most of what you don’t care about.

I agree with Jason. I think the new Control Center does take getting used to. But Jason solves that problem. His walkthrough makes things pretty clear.
