My opinion....
Not to sound like a hack, but while I (and polls) believe Obama/Biden won 3 out of 4 debates, I think Romney/Ryan emerged stronger. The first debate reset the election and transformed Romney into an acceptable president. The subsequent lost debates didn't change that or didn't change it enough to alter the new dynamic. Romney went in a loser and came out a credible president.
This is exactly the truth. Huge win for Romney in Round 1, Obama/Biden won on points with all the others, but the first one was always going to be most important.
I actually thought, contrary to most people's opinion, Obama performed better in the town hall than in the final debate; there were a number of opportunities to rebut Romney's criticisms he just didn't take (pointing out the several free trade agreements he made with Latin America, for instance), and it seemed like Romney dominated the speaking time near the end.
