The thing I've found (and through reading about) is for 433 to be effective you really need to invest in really good wingers and ST. I use Giovinco on LW, Palacio on RW and then ST I swap between IF Quagliarella and Muriel. Thinking of getting Robinho for my LW but Giovinco seems to be doing really well.
As mentioned though 433 has been my fav formation to use since I can swap quite easily between a long ball + strong counter attacks or to a short ball slow attack with a really strong defensive play.
