I have both iPhone 6+ and Note 5. My experience is that both can accurately unlocked the phone quickly. But I found finger scan on Android is pretty much useless. It only unlocked the phone. No apps take advantage of the finger scan. It is very useful in iPhone, many apps use it and I really like it. But that comes with down side. I used the TouchID too much and I forgot the actual password. I do hope Android apps will start to make use of it more.
