When reading a BTS fanfic,Would you rather prefer BTS to be like how they really are OR switch their personalities?! Please do comment and tell me your opinions

• How they are (E.G.=Suga is lazy OR J-Hope is happy-go-lucky)
• Switch it up (E.G.=J-Hope gets angry easily OR V being boring)
• Some stay the same while others change (Pls comment on who change & who doesn't
