Hard to pick "the best"... they are all nice. If I had to choose a favorite, I would pick the kallitype. It has the best contrast.
I often have the same "which process to print an image with" problem. Thus, I have done similar experiments although usually only two processes (I admire your dedication ) with similar results... i.e. no clear answer in most cases!!!!
A couple of comments about cyanotype:
It looks like you are using straight 3% hydrogen peroxide to completely oxidize the Prussian blue. In my experience this is overkill. A cap-full or two of 3% in about 500 mL of water works just fine. It might take 30 seconds for a complete reaction but it saves on peroxide.
With that subject, I like the straight cyanotype best -- but I'm certain that image would change with a different scene. And I'd have liked to see a Pt/Pd print to compare against the carbon transfer and Kallitype.
That would be interesting but unfortunately, I do not make Pt/Pd prints. Maybe if I were rich, I would I just taught myself salt printing. I might make a salt print of it...

Over achiever!!! The various salt prints I have seen over the last couple of years have intrigued me. It's a process that wasn't even on my radar before.
All the resulting images are beautiful, but my favorite is the toned cyanotype (even though I screamed No! when you started toning it ) Had never heard of 2-color gum over. Very interesting too.
