Which one would you recommend the most?

It all really depends on how much space you have, or are willing to give these puffers that will ultimately decide what would be a best fit...
So i'll list them by tank size and what i would personally get:
150 - 200G - Fahaka (very personable, and one of the bigger active freshwater puffers)
75G - 100G - Maybe a Trio of South American Puffers (Colomesus asellus) in a planted tank? Since its one of the only species that prefers being in groups and still gets a few inches long...
25G - 50G - Abei Puffer, (Monotrete Abei) although this one might be hard to find? since like the cross river, i don't think i've personally seen one for sale over in my neck of the woods?
20 - 25G Personally i would probably get one of the red eye species for this size tank, but since i think you said you don't like the red eye ones, then any of the other smaller species of puffers such as: Carinotetraodon salivator, Auriglobus modestus, Auriglobus silus , Carinotetraodon travancoricus would work...
So that would more or less be the list i would give someone who was looking for a NON-Lurking puffer..
-EDIT-
But if at the end of the day you are looking for a puffer that is at least say 4"-5" long for a tank less than say 75G, then chances are you will have to go for one of the lurker species, since it seems at the mid size range, most freshwater puffers tend to be lurker / ambush predators, until you reach up to the Cross River / Fahaka / MBU size, at which point you're also looking at tanks larger than 150G to house them....
Hope that helps you with your decision somewhat...
