Even I am planning to buy a phone in that segment, as my HTC One's screen has crashed and its speaker is also not working properly.
But I will get it repaired and will keep that with me as I love HTC but now HTC is no good, it is coming out with phones with same looks, even the M9+ looks same like my 2 year old HTC and also HTC is no good in service now. And considering that HTC sales are going so low, the company is in big loss, if their new line up doesn't attract customers then it would be really hard for HTC to stay in market for long.
S6 edge and Edge+ both are good, but if screen size is of no concern then I guess it is better to opt for Note 5.
But Samsung phones hanging problem always remains,only few of their lots doesn't lags.That is the only I am considering iPhone 6S even when I am no fan of apple phones.
