CoH is a bit more of a 'real' RTS, where WiC has no basebuilding. It gets you into the action quicker, but, I've also found it less rewarding. Enemy's will just as easily respawn with fres supply's of new weapons. I also think that WiC can be frustrating if your team isn't working together well, especially if the other IS working together. Because alone you can't do jack, with tanks you'll get raped by air cavalry, but if you have a player with you that has AA support, you're good to go. In CoH you have everything under control yourself instead. Oh, and graphics wise, WiC is equally intensive if not more intensive. Both games look very good imo.
