I find it interesting that people like Bono's voice better in the original (as do I), even though - technically speaking - his singing is much improved in the remix. His phrasing, his intonation, his control, is all so much better in the new mix. That said, it's precisely because of this that the remix lacks the character, almost desperation - and certainly a raw sincerity - that is found in the original.
Another thing I like about the original are the jangly guitars - they very much evoke the earthiness of the Joshua Tree.
