This iphone 6s is very awesome I loved it design and its new 3D touch feature you guyss must try and I will say you should buy this iphone.
Its has same features as iphone 6 but there some more feature are added like we can talk with siri without touching the phone, 3D touch and its upgraded the ram from 1 gb to 2gb ram you guyss can see the specifications in google.
Main thing is that the phone is powerful with its beauty I love the design of the phone its has great camera.
Some things are there which people dont like-
1- memory card slot is not there
2-bluetooth work only with iphone to iphone
3-cant download the songs from safari and nothing more
But thats not huge problem you should try iphone.
All in one I love this phone??
