I'm waiting for a new scanner but...
My first Leica was a CL; I later bought an M4 and M3. They were more pleasurable to use in a tactile sense. But I ultimately sold them and kept the CL.
One strong argument is that Leica lenses are now ridiculously overpriced (a V3 Summicron for $1000 plus). But the 40mm Summicron, just as good as the V3 35mm, is still reasonable in price, and is the perfect match to the CL. My main problem with the CL was the vertical hanging position, which tended to get the camera dinged, but I recently bought a Zhou case, which hugely improves this. Secondly, I've seen a hike in M3 prices, over $1000 for the M3 on this forum, which makes the CL seem even better value to me.
Thirdly, the CL has an excellent meter built in - I became familiar with it and this alone, I believe, gave me better results than my M4 plus 35mm, a package that today would cost twice as much as the CL and lens.
A key virtue of Leicas is portability, after all, and in that respect the CL is indisputably the best!
