Assassin's Creed Brotherhood asks more than Assassin's Creed II, and the gap is reads.

Assassin's Creed Brotherhood
Fixed campaign content
Assassin's Creed II
Fixed world and missions
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
