Iphone 5s or iphone 6?

I'm thinking of getting a iphone 5s or 6 but can't decide because i have enough money for a 5s but i can also get enough money for a 6 in a couple more weeks so would it be worth waiting for or should i just get a 5s

The main difference is the size. And also the 5s might not be supported in ios12 next year so you are probably better off going with a iphone 6 or a iphone SE

I think it would be better in the long run to get the 6
