From the list, I went with:
* JSA
* Sandman Mystery Theatre
* The Brave and the Bold
but a lot would also depend on the concepts and the creators involved.
If I had a fourth choice, would have added The Question to the above three.
Blue Beetle
Robin
Booster Gold
Captain Atom
Green Lantern Corp
World's Finest
Brave and the Bold
JSA
Sandman Mystery Theater
The Question
New Gods
Power Company
Warlord
Power Girl
Swamp Thing

I chose JSA, Power Girl, Sandman, New Gods, Brave and the Bold, World's Finest, Question, Power Company, Swamp Thing and Robin.
Looks like JSA by a wide margin, with Power Girl as the top solo title in second place. Interesting.
Blue Beetle, JSA and Captain Atom, but really Booster Gold would also be included because I'd make it Ted Blue Beetle with heavy Blue and Gold leanings, so Booster would be the second protagonist.
Only two books:
Combine Booster Gold and Blue Beetle into a team up title by Zac Thompson and John Timms
And also, Green Lantern Corps by Ryan Cady and Clayton Henry
