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?

The one that cradles the bottom of the main strut is useful for servicing
tires/wheels but prevents strut maintenance.

The lift point under the wing allows more variety of maintenance.
