I Purchased this phone for my friend and it impressed me very well.
The Operating System, ioS 7 which is upgradable to ioS 10.2 will give you a better experience than android.
Even the RAM is less, it wont hang anyway.
It has also a good battery life.
The design is extremely stylish and has a powerful processor.
If you are looking for the best brand name, go for it.
It wont disappoint you anyway.
