Hi Joe. I use the X-Pro1 and the XH1. The XH1 is my new favorite! I use it with Fuji primes and zooms. The big 'pluses' the XH1 provides for me are the truly lovely feel and sound of the shutter (makes the XPro1 sound like a cannon), the IBIS (which I find most useful when using adapted lenses), the tilting rear screen (I like to photograph things from odd perspectives and the tilting screen saves my knees and back), and the little top LCD screen.
I find that the XH1 pushes my photographic interests into new areas. The XE and XPro bodies lead me out onto the streets; the XH1 leads me to landscape. Love it! And the current price is amazing. I read somewhere that the low price might be a result of something like the Leica M5-effect.
