Jill Stein!
By the way, the debates aren't completely over. Next Tuesday on freeandequal.org will be the second debate between the 3rd party candidates. Yesterday was the first, which featured the top 4 (watch the whole things here: https://www.youtube.com/watch?v=lDqkenIayAI). There's a runoff vote happening on the website to narrow it down to 2 candidates for next week. Judging by the audience's reactions, it'll be Jill Stein and Gary Johnson.
The top 2 candidates are a complete joke, in my opinion. Nothing will change with either of them in office.
