i have a 5s now. and i'm still not sure. plus side for the plus (lol): landscape mode for home screen, iPad like view for mail and texts cons for me: a little big, i might drop it trying to use it one handed while walking, or since i bike ride just taking it out to check something quick. battery life? (i can get 2 days out of my 5s no problem) normal 6 pros: fits in pocket easier, can use easier one handed $100 less cons for me: no landscape like the plus optical image stabilization would be nice although i don't know how much i would use it really. the screen is great on both. since they're obviously bigger than the 5s i've been using for over a year. thanks.
