I've got both the 322 trigger and 410 geared head. The 322 is extremely fast to position, the 410 geared head very accurate.
The problem with the 322 for macro for me is when I have framed the shot and release the trigger there is a slight but noticeable droop. This isn't a failure of the head, its the pressure you apply overall to the tripod head that only settles when you take your hand off - just to clarify this is really only an issue at macro level.
The 410 geared is bulkier and doesn't have the same range of movement and is overall slower to position. However the accuracy it allows makes it a superb head for macro (as well as landscapes, astro and more).
My findings were the 322 seemed quicker to position from the off, but its accuracy had me going back to reposition the shot more than once whereas the geared head nails it first time making it more efficient and less frustrating overall.
