Using date from e+e- annihilation into hadrons taken on the (1S) and continuum, we are able to compare event properties of three-gluon (ggg) and quark-antiquark (qq») decays. By tagging radiative decays of the (3S) to the b states, we can make comparisons of the b event shapes with continuum and ggg decays of the (1S). Contrary to the notion that two-gluon (gg) events are globally very similar to qq» jets, we infer from a study of the b(J=0 or 2) states that gg event shapes more closely resemble ggg decays of the (1S), whereas qq»g decays of the b(J=1) state more closely resemble qq» continuum events in their decay characteristics.
