Doudou is from the north and speak like a real mongala, if you take someone from Equateur you will see that they speak Lingala like Doudou. About others coming from Brazzaville, some are Bakongo and only speak Kikongo ya Leta, Kikongo dialects or Kilari, which made them sound weird when they talk lingala, because they barely speak it. Other only speak Kimboshi or Kiteke. But if you listen sometimes to the songs of people from coming from Brazzaville, you will hear sometimes hear words that you will in our Lingala.
About lingala of DRC, its just that all bandleader spent the most time of their lifes in Kinshasa. But if you take someone from Boma, Matadi or Luozi and he will speak lingala, he will sound like comedian Mbatasiala or Masumu de Brende. If you take someone from Kanga or Mbuji Mayi, he will sound like Mukuna. People from Equateur have also a strong accent, they often sound like Likuli, or the way Doudou Copa talks. Those coming from Bandundu, have mostly the accent comedians Esobe, Tito and musicians Burkina Faso use.
