Considering the strength of Pak-43 to deal with any armor plus the innate flank-resistance of the OH army makes the Pak-43 pretty damn strong. Put it into shadow and nuke away at soviet tanks. Perfect bridge for the time between his T-34 and your PzIV.
It is 4 CPs. It is useful but it will never be able to bridge the time between a T-34 and a Pz4.
