If you are the person who needs long battery, quick charging and can comprise on comfort then OnePlus is the choice for you

If you are think about the built quality and durability it's OnePlus anche se oppo e OnePlus sono società sorelle la maggior parte di noi crede nel marchio OnePlus piuttosto che in oppo ma ultimamente oppo sta cercando di dimostrarci il contrario

La mia opinione OnePlus
