With dual layer disks I don't think there is a difference, at least not using the Datalife plus name to distinguish anything.
There are many who believe the DL Verbatims from Singapore are still superior to those coming out of India. But buying online, you never know which of those two types you will get. If buying DL, I always wait for the sales at Best Buy and look on the cakebox itself for country of origin.
If you have an older burner, lets say more than 2 yrs old, I would get the slower speed 2.4x Verbatim DL for better compatibility. A new burner should be able to use either.
