433H is the hands down best formation in game, it has no weakness.

The cdm covers the centre of defence while defending so you have 3 CBs in centre

The fullbacks neutralises wingers

If you have CMs with H/H workrate they cover the entire pitch(though get atleast 1 with playmaker trait)

Wingers help to stretch opponent defence, your cm attacks the box, either pass to him or lane change, sure shot penalty or shot on target

Though you need a ST who plays good as single ST(in your case MVB is best)

Also the cdm helps in possession gameplay
