About Lightning ( Mesh Plane Vs Lamp Area light )

hi id like to know why most people on youtube tutorial
prefer to use mesh plane as lightning not the lamp area light where it is automatically configured the node setup shader + the Lamp object is not visible unlike the mesh where i need to uncheck ray visibility camera + i need to add shader node emission

  1. does it have advantage and disadvantage ? ex. accuracy or easy to setup?
  2. does they behave differently ? vs the lamp area light?

id like to know some answer thank you very much for answer
