Miami is clearly the 2nd most talented team in the division. I think Rex is a better coach than Philbin but Miami is way more talented at every position aside from interior DL.
New England is my Super Bowl pick. Brady can make me a 1000 yard receiver, and there offense was on fire when they had Gronk healthy. More experience/continuity with the WR core will help there offense extremely. Brady is the #3 QB in the league, BB is the best coach in the league.
Brady, Gronk, Solder, Makins, Vollmer, Chandler Jones, Wilfork, Mayo, Jamie Collins, Revis, Browner, McCourty are all Pro Bowl caliber talents, and Riddley, Vereen, Edelman, Amendola, Ninkovich, Dominique Easley, Hightower are all quality starters.
So yes, New England is better than Miami. They've made 3 straight AFC championship games and had key contributors like Gronk, Wilfork, Mayo on IR.
