I have a 35S that I enthuse about periodically.
It's something of a love/hate relationship. I love to shoot with it, I love the way I shoot with it, but my distance estimation sucks.
I tend to hold it waist-level like a TLR, fiddle with exposure, DoF, and distance, then bring it eye level and compose and shoot. In good light, if you stop down, you can get away with a lot. Unfortunately, I like a little bokeh, and you can find a lot of people complaining about front focus issues on Sonnars on any camera, and I think between front focus and scale focus I have recurring issues on average days.
My light meter tends to be pretty reasonable:

...but with the 35S the battery compartment on the inside, my battery is almost always dead, so sunny/16 is my friend:

I've had good luck with the Wein cells, but I've started just using size 675 hearing aid batteries (

If I'm honest, I think the number of decent shots per roll is lower on my 35S than my other cameras, but I also think maybe half of all my decent shots are from that camera as well. It would be the first camera I would take as a wedding guest and the last camera I would take as a wedding photographer.
As an aside, it also made me love 40mm lenses. To me, 50mm is like, "This is what I saw," and 35mm is like, "This is what it felt like," and 40mm is, "This is what it was like to be here." I suspect if I could score a Bronica with a 65mm lens I'd love that FoV all the more.
