I know and use fuji ca-- and would be reluctant to switch to anything else if for no other reason than fuji has the best lightfastness of any ra-4 paper-- just curious/intrigued to see something new, which in the world of chemical colour is pretty rare, let alone colour darkroom.
I have no idea of who makes this. Mitsubishi and Ilford Switzerland are
the only other mfg of RA4 papers I'm aware of, besides Kodak and
Fuji. Mitsubishi markets lower-cost papers across Asia.
I'm pretty confused about that as well...but all signs point to it just being Fuji Crystal Archive Type II. It has the same base, same general exposure parameters, etc.
I have been wanting to try it since seeing it appear on B&H. Appears they're being drop shipped from somewhere. Shipping price to Canada is making it more of a risk. I'm thinking that I should just stick with Fuji. Price is pretty much the same anyhow.
Even their B&W papers really pick at my curiosity.
