The key advantage of the H55M-UD2H is its Firewire support, and while this is not a lot to go on as not everyone is going to find this feature useful, its absence on the P7H55-M Pro gives Gigabyte the edge. Additionally, Asus failed to provide DisplayPort on the P7H55-M Pro where as this feature can be found on the H55M-UD2H, improving connectivity further.
