I like my Fuji but it only works for certain subjects/methods of shooting so mine isn't going to get much use from day to day. However the lens on mine is so blisteringly sharp, without doubt the sharpest lens I've ever used and I know that if I sell it, I'll wish i hadn't.
I took my Fuji and my 5D to New York and i got most of my better shots on the Fuji as it was the right system to use in that sort of environment. In that sense i can see how you didn't get on with yours. However I reckon you should give it a little more time, don't treat it the same was as your Yash Mat as it's a completely different tool, like saying you prefer your hammer to your screwdriver.
I just need to work out a good film to use with it as the films I use with the RB are too clean for it, if I'm shooting hand held on the go I normally want a bit of grit in the shots, so it's going to have to be something like Tri-X.
