I had both, but the IQ, colour, sharpness, almost everything seems to be better on the Fuji 35mm, so I ended up selling the Ziess 32mm for the new Fuji 23mm f2.0.
Very happy since the 23mm is perfect for street photography and the 35mm for generally everything else.
I'm not a big fan of Ziess lenses, since I owned a few before, for Nikon cameras and always ended up selling them. A better choice for 3rd party lenses for me is Voigtlander - not all their lenses but some of them are amazing, specially for Fuji.
My opinion anyway.
