I didn't watch either, planned on it but life got in the way.
As far as winners - I don't know (can't tell you my thoughts cause I didn't see it), but I have looked and depending on who is reporting this there are different winners and losers. Almost every single candidate was chosen as being a winner at least once and almost all as being a loser in different viewpoints.
I found that kind of funny. I think all or almost all thought Carly Fiorina was clear cut winner. Again didn't see that debate, but I was fortunate enough to attend a women's leadership conference where she spoke and one thing I can say she is an excellent speaker -- I would not mind hearing her speak again.
