John will always be the Green Lantern for people in my specific age group haha. And I will always think that Aquaman should have a manly beard and hook-hand as well :P 

Wally West was my favorite as a kid, and Superman and Wonder Woman have grown a lot on me. Question is also one of my favorites. As is Doctor Fate. And I have a somewhat odd favoritism for the somewhat obscure Gypsy and Doctor Light. 

But then again I like almost every hero. Except Guy Gardner, who's kinda annoying. 

If Amazo was like the JLU Amazo he'd be the most OP hero in the history of ever.
