I think ACR is a 7 whereas AC3 is a 6. Constantinople was beautifully designed, but there was less content to keep you busy, so it felt kind of empty. The Altaïr segments were disappointing. The supporting characters were lackluster. The story had a lot of wasted potential. The Desmond sections were all right. What saved the game was the great atmosphere, taking over Templar dens and some fun freerunning and stealth missions.
