I think it's a toss up who will have a better record this year. Bengals or Eagles. Both should have relatively tough schedules as division winners, though the Bengals probably have a tougher in-division schedule. Eagles have the better coaching staff. Bengals likely have a more talented team, but that is debatable.
If I was betting, I'd say the Bengals win a max of 9 games. Anything over 10 or less than 7 would be surprising.
