How good is iOS7 on the iPhone 4S?

Hi, I like iOS6. I want to upgrade to iOS7, is it as fast as iOS6 on the 4S? Like is it laggy at all?

Nope its amazing

I updated and mine is absolutely fine, it runs smoothly with no lag but I do not like the design, i prefer the io6 for looks but for function I have had no problems so far.

I downloaded and installed it today on my iPhone 4S and it has been working just fine! Maybe it's justtm imagination, but it feels like it's even faster than it was before.

I just didn't like the look of it at first, but I got used to it pretty quickly. All the functions are much easier to access now.
