Hey there Kates,
Not sure if this is going to answer your question, as I am not aware of those configurations all being available in .357.
However, in the .44mag. the "Super Blackhawk' was a bit heavier then the standard model, plus the cylinder was not fluted, the trigger guard was squared off at the back instead of round as in the standard model.
On the "Hunter" model, it shared features from both of the previous models. The Trigger guard was like the Standard model while it had the unfluted cylinder of the Super model.
Also on the Hunter, the barrel featured a solid rib - part of the barrel - which was machined for Ruger rings which came standard with the handgun.
I have only had a standard model in .357 cal, but a number of Supers and one Hunter model in .44 mag.
I expect some other posters are likely to add some other tidbits to this info.
Keep em coming! :-)
