None of them Id say pick custom characters with different options for voices.
I can safely say in context of the series I nor any of my friends found any value in any of the current 8 characters. Of course many hilarious things have been done with them outside of the context of the game, but they were always such weak sauce to me that I would have rather just had a character builder and made my own.
Because ten out of ten times if there is a character you want to play as, it is already selected, and then you get the scraps. I want to be Francis no you get to be Louis, Fine I want to Be Nick, no you get to be Rochelle. ffs
