MSI b450 gaming plus motherboard or Asus tuf b450 plus gaming motherboard ???

both are good brands i think choose your motherboard by concerning port and other features (there was a faulty asus B450 shipment in mid of this year and most motherboards were refunded so be sure this mobo is not in that stock )
my personal recommendation  is go for B550 if your going to use 3rd gen ones
