ZYX 4D new cartridge. Best yet ?

Just out and regarded as there best yet ? any feedback
The 4D is the same cartridge as the Atmos, just with a different name (for some reason it's sold as the 4D internationally and as the Atmos in America). The UNIverse is still the top dog of the ZYX lineup.
Patrick is correct.

The 4D is identical to the Atmos, the difference is in name only and strictly for marketing region purposes. This isn't what non-USA dealers will tell you, but they can't sell the UNIverse...

You can read reviews of both cartridges under my signature.
If I stand corrected ZYX cartridges are not sold by dealers, but are sold direct. I know I use to deal with Jay Bertrand way back when.
