Difference between H110i GT and H110i GTX?

I've not been able to find any solid information on the difference between these AIO's.
Looking at Corsairs website, they seem almost completely identical so i'm confused why two even exist.
Apparently the GT is better due to the firmware or something, and it's £20 less, so I'm inclined to pick that even though it's slightly older than the GTX. Any advice on which is better would be appreciated.

The 110i GT is OEM from CoolIT, while the GTX version is from Asetek. corsair claims the gtx is quieter, though the airflow in the gt is a bit better. Go for the cheapest one as they perform the same.
