The only problem with warcraft3 is that the counterability of unit types is exagerated. Let's say you get a bunch of archers and the other guy gets a bunch of footmen (with defend which means 75% percent less dmg delt by peircing therefore archers), you are dead no matter how good you are controlling and managing your units. In SC, if you're smart you can still have a chance !
Its how do you say ?
A deal's a deal !
