Of those I've seen, Moē, no contest. :-)
But I recall discussing Hoshi with Wilson & Yuki once and they described her as "really LOUD". I'd be surprised if anyone outdid her based on the way even they were surprised.
By the way, I saw you posted about having the honour of farewelling Hoshi yesterday. From the roster I'd have been in the waiting room right about then and was actually surprised how eerily quiet the place was, must have just missed hearing it and being able to compare for myself. :-P
