I know I'm taking bait when I see a phrase like "JD was about creating music; NO was in [sic] creating the Hacienda". But anyway.
I love JD but it's got to be NO. I think the OP's characterization of NO as insubstantial dance band versus quite misses the point. JD's approach was to make something beautiful from the darkness (and they do). NO (well, pre-1990) instead combine multiple feelings and sensations, pleasurable and painful, into a single song, which is what makes their music so lasting and fascinating to me.
A song like The Perfect Kiss (12" version), if you really listen to it, isn't made by a band that doesn't care about "creating music". On the surface, sure, it's dancey, but it's got incredible depth of feeling in both the lyrics and the music (which is all the more apparent in the video). It's a sad melody with dark, oblique, lyrics married to an insistent beat and excting, pleasurable cadences. It's hard for me to explain, but that to me is the genius of New Order, the presence of the joy and sadness and longing and fulfillment embedded in the music. I realize not everyone's ears are going to be attuned to it, but there's real emotional richness there.
As a lyricist, I think Ian's lyrics are very poetic, but I think that Barney's are, in their own way, equally thoughtful, at least through True Faith. (Technique has its moments too, but it is inconsistent -- after that, the writing became much more obvious and literal, as well as grammatically awkward -- it's impossible to imagine "Turn My Way" or "Hey Now What You Doing" coming from 80's New Order.)
I think NO's lyrics are in some ways more abstract than JD's, but rather than that making them meaningless, to me that makes them powerful -- I can't always get words around what he's singing about, but I can feel it. To me, that's real art. (My girlfriend will occasionally ask me "what's this song about"? And I always shrug and say "I dunno, but I can feel what it's about."
Anyway, they're two different bands, really; it's not hard for me to imagine a Joy Division fan liking New Order any more than it is for me to imagine them liking some other band. There doesn't have to be an implicit comparison of the two.
