To this day my S6 was the phone I was actually happiest with. Mostly just because of its durability, fit and feel (and the screen of course) rather than any particular tech spec.

I am stuck on the (still working) S7. The physical home, back and application view button just feel so nice, that and the size, it actually fits in my hand, and pants pocket too.

I loved the feel and size of the S3. The rounded and smooth back felt great in the hand and you could throw that thing around without a case and it took it like a champ. If anyone make a modern phone like that again I'd buy it in a heartbeat.
