in my opinion yes.
6s+ from 6+
6+ was like a 5s driven phablet, exacerbated experience
no tab reloads to worry about, no music skipping while doing stuff which would happen all the time, digital record skips is no bueno, handles my tons of jailbreak tweaks beautifully. feels like an iPad air2 in my pocket, which I also have
if 7 design is underwhelming and/or this one omits headphone jack, I may stay on my 6s+ for a while. Internally its a beast!
I'm tired of quality control hurdles every release too
new touch ID is fast as heck, and 3d touch is nice with some jailbreak activator gestures, better camera is better a bit *surprise* but 6 was no slouch, and yeah.
gimmicky as it is, i like live photos
I also like the haptic motor more than what was in 6+, it seems more solid for notifications and such
2GB of RAM alone made it a necessity
