Which division is stronger? AFC East or NFC North?

Looking at how they did last year. AFC East had the Patriots go 16-0, but there was no other team above .500
The NFC North is usually called the weakest division and the 1st place team Packers were 13-3 yet there was no team that went 1-15.

What division do you feel is better (not team)? Why?
