I do a mix of both with a priority to roleplaying. I'm in the willpower self insert category. I only really like playing "what would I be like in this type of world". Don't want to play as anyone else but me. I don't like power gaming that much because I like the thrill of fighting and I hate one shot kills. It really destroys my enjoyment either dealing or receiving one shots. I have a strong background in math so I don't get "excited" by crunching numbers either.

Hell I saw a barbarian mod video earlier today and it convinced me to make a bear beast totem half elf with hermit background, skilled feat for rest of wisdom skills, and sentinel feat if added. Not exactly min max, but I will make the wisest but not necessarily the smartest barbarian ever. I like utility over damage so I really hope larian leans that way too.
