Well, this certainly looks intriguing 

I haven't read it either, but I have most of the issues in my unread back issue collection. Some of them were co-written by Mark Waid which makes this storyline one of the few times Mark was allowed to write Superman. The main writer, Tom Peyer, is also pretty good and was one of the co-conspirators in the proposed Superman 2000 revamp ( http://superman.nu/a/ges/2000/ ) along with Waid, Mark Millar, and Grant Morrison. So I bet it's actually pretty good. I'll let if know what I think if/when I reach that storyline in my back issue readings. 

This looks interesting

I do like the Adam Strange one, can't say I know anything about any of these.

i like this series it was nice, have to say when he was a gl i never saw him use the ring as a shield once it was mad. if superman was a gl man alot of ppl would get smoke his powers with a gl ring that was a nice concept the cape thing was a bit corny since i cannot think of ever seen 1 gl with a cape

I'd buy it.  It looks...intriguing.  

That last cover is crazy, why didn't they color his skin green?
 
I'd check this one out at least.
