I went from an S5 to a Nexus 6P which had Bluetooth issues interfacing with my vehicle, so my carrier swapped it out for me for an S7. I like that it is the same size as my S5 - I'd gotten used to the form factor and hadn't acclimated to the 6P yet (note that aside from the issue, I'd have been perfectly happy to stick with the 6P, even though it doesn't have image stabilisation - it DOES have the universal radio (I travel).
I would not have paid the extra money to go to the edge, but for the fact that the battery is bigger.
I find that even though the reviewers seem to think the S7 has a big enough battery, I don't. Perhaps when I win the S7 giveaway I will find out, because I would choose the edge. Until then, the base model is fine.
I DO have concerns about constantly tripping the edge widgets by accident . . . . of course when I win and if I don't like it I'll be able to go back to my S7 . . . . .
