For me the greatest difference is that superset is terminal-centric while conductor is chat-centric.

GUIs slow you down, in my opinion. But having the nice visual diff is something we can't really do well in TUIs, so very welcome.

So, superset, for me (been using for quite some time now) is basically to organize my agent and terminal sessions per task and project.

I can switch context much easier and can also resume working on something days later, with all my tabs nicely available and separated.

This was consuming me before, a dozen or more tabs and windows in my computer that I don't really remember to which task each belongs to.
