I've got about the same amount of variety - Everything from the "Hasselblad - (Zeiss?)" to unnamed Japanese, with a Heliopan or two thrown in. In all honesty, I can't see a damn bit of difference between any of them.

One possible exception - the Hasselblad Softars ... (appear to have bubbles in the surface) seem to soften differently than others - frosted and the like. The difference is subtle ... and I'm not sure worth the price.
