The iPhone 5 fared a lot better in drop tests than the 4 or 4s. The glass back on the 4 and 4s was a huge problem if you dropped your phone from a distance. Also the 5 is silky smooth as far as responsiveness goes. Yours must have been defective. Also, the speed difference between it and the 4s is very significant and is a pure joy to use. The colors are so richer compared to the 4s. Mine came without any issues but my wifes iPhone 5 has an issue with the + volume button getting stuck a lot so she will be going to get a replacement in a couple of days. It comes with a warranty so if there is any issue I can get it replaced anytime an issue comes up. I'll say it again, the increased speed, bigger screen and lighter weight yet solid are all major upgrades over the 4s.
You have to remember that people usually go to the Internet when bad things happen. I have bought many products that I really liked but never really bothered to write a review online about most of them. Now on the other hand, the few times I bought something I didn't like, I wrote a negative review most of the time. People tend to bring out the bad and not talk much about the good. My advice to anyone is to get one for yourself and then judge it. It's a sweeeet phone!.
