So it's a stufftier version of the recent CoD series.
Not even close. How does that relate to COD at all? In COD everything is a camping spot, in MOH they aren't as plentiful. Or if they are, they are easily avoided/outsmarted (Unlike COD's where it takes flying across the map and through a labyrinth to get to some spots, or when it's a TINY crack in a wall where you can't see them, but they can snipe you perfectly). This is multiple times better than MW2 IMO.
There aren't as many guns, nothing is really a "cheap" weapon. Shotguns are very balanced. They usually 1 hit KO if you hit on target okay, but take long in between shots to reload/pump. Maps are spread out a bit more. Not everything is cover and/or a cluttered mess.
EDIT: What I meant by the knife thing, is don't go up to everyone and try to knife them and expect to kill them every time. It doesn't work like that. When you knife and someone is 10 feet to the left of you it won't kill them like it does in MW2.
EDITEDIT: Yes I exaggerated on a few things for MW2, but you get my point.
