I think the Summitar looks soft low contarst even with the hood. The summicron I like. The elmar and tessar look similar to me I don't mind either. I just hate leica summarit so I sold it . I like summaron 3.5cm I tink its a little soft but I still like it.
I'd agree with that description about the 6-element 50/2 Sonnar design, from my limited experience (mostly with the Nikkor-HC version in LTM), but the 7-element 50/1.5 with slide film strikes me as very "classical"-looking. It depends greatly on the lighting, though; looking quickly over the shots I've used it for, I find that my favorites are either from hazy days or in oblique lighting. On a bright sunny day, the Nikkor seems to handle the contrast in a more "right"-looking way. All IMHO, of course, and with a lot of other confounding variables.

The f2 is six elements and the f1.5 is 7 elements added in the front right?
The rear cell of the f:1.5 is a triplet, in the f:2 it is a doublet. Both the f:1.5 and the f:2 have four internal surfaces, this was important before lens coatings were widely applied.

Love my 50/1.5 Sonnar, it's a pretty late one. Really nice signature on my IIa:

Here are a couple for observation. The Jena 50/2 is no slouch but, IMHO, the 50 1.5 outshines between 2.8 and 5.6, and the full open f1.5 painterly "look" or "glow" is not quite attainable with the the F2 Sonnar. Still, they are both wonderful lenses to use.
Opton Sonnar 50 / 1.5 wide open at about 1m on Tri-X @1600
Jena Sonnar 50/2 wide open at about 1m on Ektar 100
EDIT: I should add that I use a 1A or 1B skylight on every lens, so the warmth in these photos is not accurately representative of these lenses sans filter.
I had a couple Summarits, mine were very clean. They were a bit 'weird' wide open, but withal a good example of the double Gauss type. AFAIK, the Summarits were all coated postwar examples of the prewar uncoated Xenon which was actually made for Leitz by Schneider and a real handful as regards flare.

The f:1.5 version is somewhat of an anomaly, actually being regarded as better than it's slower sibling!
I think the old Sonnars are aptly named, there's something bright and cheerful about them. I see this in my J-8 as well.
