Spring bars will nearly ALWAYS be the lowest pint since they MUST be lower than the trailer frame for the principal to work.
Ummm, no. The spring bars do not have to be the lowest point on the hitch assembly, they just are with most setups. In theory, a hitch could be designed to put the bars over top of the trailer frame rail pressing down on the tongue, but the setup and installation would be pretty difficult. Also, there would be more challenges clearing tailgates and other hardware on top of the tongue like jacks, battery trays, propane tanks, etc. Also, the bar mounts would have to clear the tongue as the trailer swings on the ball... Point is: It *could* be done, but I don't see any significant gains there... But I digress...
Under-hanging the bars, on the other hand, there's usually plenty of clearance there under the tongue for all the necessary hardware without clearance issues, save for low clearance on the ground in some setups.
The Equalizer or the Reese SC Trunnion are probably the two with the most ground clearance. Similar in design and function, though I'm partial to the Reese myself.
