Both have the real potential to be wonderful or painfully awful! I would perfer a good dj over a bad live band and vise versa.
As a whole however, I would be more attracted to a dance hosting a live band.
There's a certain energy a good live band brings-- it's happening in the here and now-- just like the dancing. There's something sorta fun when the singer flubs the second verse a bit and looks around to see if anyone noticed-- then sees that a few people did... it's just a different dynamic.
I like having a moment in between songs. This gives dancers time to find their next partner and/ or clear the floor befor the next song starts. DJ's could do this-- it's been my limited experience that they tend not to. One venue I attended the dj actually would slightly overlap several songs in a row.
A great advantage to a DJ'd dance is that we can dance to the sounds of Count Basie, Nat King Cole :swoon: (sorry-- had to through that one in there

), and so many of the greats and a greater diversity in artists and music types.
-- Personally I'm not much of a fan of throughing in contemporary music into a dance. I know lots of people like it. My favorite music is swing/jazz and I'd actually perfer to listen to it the entire night. I realize I'm in the minority on this os I deal with it. Perhaps that's why I perfer live bands in that if they're playing a swing venue they are more likely to stick to just swing than a DJ perhaps. But then again, sometimes they play a cha cha then I take my water break. :shrug: It's all alright with me.
This is just my onpinion. I'd love to see what other people have to say about this topic!
