In the past I've owned an R6/6.2, R7 and all of the Leicaflex series. For weight reasons I mostly shot the 35/90 Elmarit's (f/2.8) and the 50 Summicron (f/2). The R3-R7 are pretty much like their Japanese counterparts. The R8/9 is unique; an ergonomic masterpiece with a very good viewfinder. The Leicaflex series are great mechanical cameras, albeit large and heavy. The Leicaflex SL (which I preferred) has a big, bold, beautiful viewfinder, where things just pop into focus in a magical way, and an incredible braking system which allows hand held, slow shutter speeds. Wide open, hand held, 1/15 is very useable. I put a lot of film through a pair of these, but maybe not quite reliable as say a Nikon. As far as optics, I suppose Leica lenses are a bit better, especially at wider apertures, nicer bokeh in some cases, ect., but over the years, especially since I shot only B&W film, knowing too that light and composition are primary, I've jumped off the Leica bandwagon. I can get just as good a picture with an old $50 Nikkor then I can get with an expensive Leitz. Maybe a bit sharper, definitely heavier, but frankly, for me, sharpness is way overrated, and the Nikkor, ect. are all sharp enough, at least for B&W film. I liked all the Leica lenses I used, but there are some Nikkors I just don't like how they paint, so there's that too. Try them out; make your own decision. In sum, maybe Leica's are "better" in some objective sense, but not sure it's worth all that extra money. You can take good pics with any camera.
