Interesting question. For me, they both have equal aesthetic appeal and both have a huge back catalog with countless wonderful b-sides, and both can be fearful, melancholy, upbeat and fun. To me, though, The Cure win because of the sheer length of their set lists and changing things up, and (more recently anyway) adding more gems to the sets. Depeche always pretty much stick to the same formula and only do the change up thing to any great extent with Martin's solo songs. Maybe Robert can just remember lyrics better than Dave can...
