SCCM wins every time for me, once I've got my image set up and captured I just sit down, click a few times to target which machines and want and let them get on with it. Complete reporting straight out the box so you know what's done and what isn't with no need to start anything manually on the client. Add that to all the other systems management and software deployment goodies you get with the product and low price on EES you can't lose imo :)
