I switched back from Prompt to iTerm. Prompt is awfully nice but has enough bugs and rough edges (which I've reported to Panic so they can fix them) that I'm not yet comfortable with it as my daily driver.
Massively more configurable, and generally more features. Use iTerm if you'll enjoy trawling through all the Preference panes and menus to tweak and find neat stuff.
I just use the default terminal that comes with macOS but was considering trying one of these ones.
