Are public defenders reliable when fighting a federal case? What are the pros and cons to then?

I am currently fighting a felony case with 9 counts and was appointed a public defender because at the time I couldn’t afford a private lawyer. It is a serious offense and seems like it could carry alot of time if convicted. Is it best to try and get my own defense lawyer or can a public defender get the same results?
This is my first offense

Public defenders get a bad rap. Many of them are fantastic and in court or trial more than private attorneys. That being said it will depend on their experience and case load. Low experience high case load means little time for your case.
