First of all, somebody expressing an opinion which differs from yours is NOT them taking a "cheap shot".
Secondly, you mention that Nikon and Canon cameras don't have "perfect" reliability, with the inference being that your beloved Leica cameras do, when even the most cursorary glance at the various threads on this particular site should have disabused you of this erroneous notion long ago - and yet this has clearly has not occurred.
What this means is that you have a clear bias (nothing wrong with this provided you are able to see it and understand it as being such for yourself), which may very well prevent you from being able to understand the answer to the question you pose. I would suggest however, that it would be worth looking beyond just the camera bodies (though no unbiased party could dispute the features and specifications of the Nikon D3x are far beyond those of the Leica M9) to understand the view that Leica is expensive (which is far less subjective than calling them "overpriced"), and look at the pricing of lenses as well.
