The 6S and 6S plus didn't offer a ton of new features really besides being faster. The 3D-touch screen is nice for quick shortcuts but not a killer feature. Basically, the only reason why I would personally want to upgrade is for the bigger screen on the plus model and the battery life that comes with it.
