drop shot, you have one, so you should be able to see for yourself!
. Seriously, the obvious ones are the dual action swivel clamps which can accomodate any string pattern or head shape, unlike the Neos and the more secure frame mount on the Gamma. Since there are more points to align it is a little slower to mount the frame than it would be on a Neos. The dual action clamps take a little longer to lock than the single action clamps on the Neos, so again there's a slight advantage in speed for the Neos. There is never an issue with blocked holes or having to maneuver around side support arms with the Neos because there are none.
