Harnesses try to solve a wide range of complex, open-ended UX problems, so there isn't a perfect one. CC might be the best one I've used if I give each major UX aspect a rating 1-5 and then average them. For example, it has a decent subagent viewer. Meanwhile, Codex doesn't even have one, and its subagent tool call is so buggy that the parent agent sometimes doesn't even know why the child died. Being a TUI is very limiting, yes, though that limitation isn't the harness' fault.
