I don't know what definition of TUI we're using, but if we're talking about ncurses style whole-terminal-window GUI, there's no inherent advantage. Responsiveness being limited by character width actually sets harder limits for "TUI"s. It does favor the kind of text-centered UI done by Oberon-1 and imitated by Plan 9's ACME, where there's little to no use of x-y addressing and text just flows.
