I've read all those things, and I stand by what I said. YJ was fine, but it was actually a huge regression to all the growth he was getting under Kessel's run to keep in with the sitcom tone of the book (which I enjoyed when I was a kid, but don't really anymore). Adventure Comics was also fine, especially with Francis Manupal's art which perfectly conveyed the "country, Americana" tone. But there was nothing that interesting about the character again. He's just a Clark-lite. Also, I've always hated the Lex-clone retcon.
Lobdell's Superboy is the most unique he's ever been. He has an abstract conscious, giving him a unique and detached POV on human society. Like something from a Warren Ellis comic, but without the right execution.
