I have used both. Know the resulting image will be the same and I have noted no difference in focusing with latest firmware. But it's all about handling and the OVF. I have medium sized hands and found the buttons on the XE-1 cramped my use of manual focus. I purchased a used X-Pro after returning the XE and it works better for me. Just more room to maneuver. And it reminds me a lot of the feel of my old Digilux 2. The other issue with the XE is when using the zoom package it's somewhat disproportionate as the lens scale is large for the smaller body. If you plan on expanding your lens collection in the next couple of years take this into account as some lenses will be even larger than the 18-55. The only accurate way to decide is handle both and see what works for you.
