As stated previously, the difference might be small, especially in an untreated room (featuring early reflections arriving from various directions). If you isolate the direct sound using gates, you´re likely to see up to 5 dB difference in the highest region. Below about 2-3 kHz, the ECM8000 (according to the test linked to in previous posts) is truly omnidirectional and direction does not matter.
