I've never really tried any of these, also stuff like Challengers of the Unknown. Or any of the other 4 man team non-super hero silver age DC adventure books.
I'd like to pick up a collection of 1 or 2 of them. I can't afford them all, so I'm looking for opinions on what the best ones of them were. Please feel free to include any I've forgotten to name. I've already tried Mystery in Space, Suicide Squad and Doom Patrol.
Thanks in advance.
