Not many hands on villain, around 6 but he was a 60/30 and seemed pretty aggressive.  I decided to 3bet him which is my standard line and someone said they rather than flat than be in an awkward spot of 5betting or flatting a 4bet OOP.  I believe that's poor thinking to not give yourself an opportunity to win without showdown.  Thoughts on the 3bet and decision to flat, 5bet, or fold.
