The one that picks up the jack cones on the wing spar is preferred..

The strut adapter type will not enable inspection/servicing the gear
struts and mounts.

Thinking about buying a wing jack for my Archer. I see a couple of designs
sold by Spruce, one a simple hydraulic jack with an adapter for cradling the
bottom of the main gear strut, another designed to catch the coned lift
point under the wing. Is there a reason to prefer one style over the other?
