1) why is one tomato going great and the other no?

Luck.

2) is this dying tomato ever going to make a comeback?

I doubt it, not if it's been in a month.

3) should we rip up the dying tomato and plant a new one - is it too
late for this?

It's not too late if you replace it with an advanced seedling, but as it may
have been suffering from an infection, do not plant the new tomato plant in
the same place. In fact, it's better not to plant any member of the
Solanaceae in that spot for a few years (potatoes, eggplant, capsicum,
tobacco). Why not a zucchini plant?
