i had the feeling you'd drag me into this, Marty.
i've been trying to give this a lot of thought, actually...i keep coming across this topic and not really knowing how to respond. there are a lot of moments throughout the span of their career that i've thought were really brilliant and which affected me very strongly.
upon careful consideration, i think i'd have to go with everything from PCL-Brotherhood. but it's a difficult question...the things i like most are when they'd just got themselves together as their own band, and had got away from living in the shadow of The Other Band ( :D ). mind you, i love JD. but they really needed to get away and reconsider and regroup themselves...and i think most people here would agree.
at the same time, there's a certain rawness and uncertainty that's really interesting to me in the earlier recordings...i agree with whoever it was that said that Technique and Get Ready are good, but different in many ways cos they're so polished. there's a different sort of energy that i really appreciate in earlier stuff...some of Movement is a bit too uncertain, too much in the shadow of the past...but as someone else had said, there's also the glory of "Ceremony." which of course is a bridge, and therefore there's no point in even trying to escape the shadow. ;)
so many moments...so hard to decide! i think if i narrowed it down really tightly, i'd come up with Low-Life. despite the abomination that is the choppily edited version of "The Perfect Kiss" on it. 
and if i narrowed it down even further? favourite moment ever? might well be "Face Up." 
though of course, there are other moments throughout their career. so it's a difficult, difficult question, that. and even though i've attempted to answer it, i'm still not entirely sure how to answer. if that makes any sense.
