I've only read Superman & Superboy so I wont comment on the others.
1. Superman - Really enjoying this series, Good writing, Good Stories, Good Art
2. Superboy - Just couldn't get into it, too attached to the original Clone Superboy I guess. Felt some of the changes were just changes for change sake. There was no need for an new Organisation called N.O.W.H.E.R.E. considering that it is almost a carbon copy of the Agenda. I would have had the new Clone Superboy being a experiment stolen form Cadmus by the Agenda.
