Wow that really makes the whole thing even worse than I thought. Editorial should've never let it be published, not like that.
Overlooking that - which is really really awufl - and there are things I wasn't crazy about post Crisis, like getting rid of the Superboy era which forever screwed over the Legion, but overall I really enjoyed Byrne's run. His updates for Superman and the supporting cast really breathed new life into them and brought in new facets to them. I think every fan of modern day Superman should read it.
