I am using iPhone 5s for the last 6 months and I must say it is still better than some of the low budget phone. It has minimum lag and very high touch performance. Moreover, steel body of the phone makes it one of the best looking iPhone.
It has many features that are extremely useful. Moreover, sound quality of the headphone is better than any other android phones. Back camera of the phone is 8MP, however, it is better than some of the 13 MP phones in the market.
