It's hard to choose because each of them got like 1 personality while i'm myself got different character so I guess when they are together it makes it more special. but yeah Applejack is awesome ;3 her accent remind me Engineer from team fortress 2
It's hard for me to pick a favorite cuz I like all of their personalities But maybe it's AJ's accent that really gets me. Yup, both the Engineer and Applejack have that southern accent. Engy's is Texan and AJ is... from Equestria.
