lol yes... the 6 are a noticeable upgrade from the 5c (which is really a 5 inside - even though it was released at the same time as the 5s).
I noticed the upgrade from my 5 -> 6 very easily... 6s is a very nice speed bump over the 6.
I went 5 -> 6+ -> Galaxy S6 Edge -> 6s+
I was eagerly awaiting the 6s release as I couldn't wait to get rid of the S6E
- Terrible battery life that wouldn't last a full day
- Only phone I've ever used that needed a case
- Android is not as good as iOS, not even after years of following in its footsteps
- Battery battery battery
The speed of the S6 was a nice bump over the 6+... the speed of the 6s+ is about the same as the S6.
