I have the Statement for some time now and I like it a lot. It has its specialty - female vocals, and that is what I mostly use it for. I would not keep it if it was my only cartridge, but then again I have yet to hear one that I would have as my only one.
I am not sure if it is worth the price difference over the Reference - it is for me, but YMMV.
