Don't know about similar game. Men of war is too much micro. Starcraft 2 is balanced but it is different genre.
I too have yet to find a truly very similar game to the CoH series as well. If it exists, it seems to me no one knows about it. While there are certainly many RTSes based on many wars, none others provide the same feel of on-the-fly terrain interaction, positioning, movement and preservation to all of its mobile units (in most RTSes for example, basic infantrymen are based largely entirely around spam or garrisoning defensive buildings and in many cases will be rendered obsolete entirely by later units. In most realistic RTSes, infantrymen are plodding snails to prop up your lines, fill up defensive terrain and get killed so your more valuable units won't [...just like in real life, but that's not very fun])
