Iphone 4s ios 7 slow response

I want ios 6 back!!! Having ios 7 on 4s is pain in the as* this is not the way i want to use my device. Having 20% less if not even more on 4s is not funny. Apple should think about this. Cause there are some people that use older devices. Personally i am dissappointed by this and all i want i to have old and stable 4s on ios 6. Thank you!
