I owned a pair of the same C1's for a while, but eventually returned them. The eye cups would not hold their position and IMO the field of view was not as wide as advertised.
Having said that, I am not surprised how well you regard their image quality, compared to the Leica. The Maven C1's have incredible image quality.
Strangely enough, I very briefly owned a pair of the new Leica Trinovid HD's and returned them for the same two reasons - narrow FOV and eyecups did not extend far enough for the amount of eye relief. I guess I'm sensitive to those two features!
