hey,
I just went from the 5 to the 6s
Functionality pretty much the same...
Main diff is size and chipsets and 4G
From memory the 5s supports 4G - check your data package plan to make sure you have the correct one!
You would be amaze hoe quick you get use to the bigger screen and better it is!
I would go for the 6... who says bigger and faster is not better :Clap:
If not too expensive consider the 6s
