I most often beat VC with WoC by killing the General. If you can take out the characters who are both stopping crumbling and resurrecting troops then VC fall apart without you needing to fight the units that are difficult to handle.
Against Skaven I suggest Hellcannons: area effect panic causing shots against low leadership blocks will at worst trim them down before they reach you and at best start a chain reaction.
Against any large block I suggest using terrain to pick your fights. Hordes are difficult to manoeuvre so you can aim to get flank and rear on one without another being able to counter-charge; this takes away most of the attacks and the rank bonus so you can blend in safety.
