Does it? Sure it grips twice as many studs, but does that mean twice the
gripping power?

Well, it’ll be affected by the fact that the 2x2 version has considerably
different internal geometry than the 2x4 version, but the 2x4 version has
much more sturdy geometry than you’ll find inside either a 2x4 brick or
plate. It’s built like a 2x2 brick with 1x2 plates welded on the side, so
the four inner studs are gripped roughly the same as with the 2x2 version,
but the outer studs are gripped by four points instead of three, and none of
them are the more flexible large tubes.

Even if double the studs mean double the grip, the piece adds more height,
which gives better leverage for getting the piece off whatever it’s attached
to (a 2x4 brick is less secure than a 2x4 plate) and counteracts (at least
part of) the extra grip.

True, I was thinking in terms of pull strength rather than shear strength
(attach one to a 2x4 brick and see if you can pull them straight apart
instead of levering one to the side), but I did notice two days ago during
the trial BrickMech game that Peter ran at our MichLUG meeting, that the 2x2
tile version popped loose a few times while the 2x4 version never did.
Anyways, much of the perceived additional gripping power of a plate comes
from the fact that it’s harder to grab it than a brick, but the 2x2 tile
w/pin loses much of that advantage by virtue of the fact that it’s got a pin
sticking out of it to provide leverage. In fact, you get more leverage from
the pin than from a brick’s wall because it’s in the center rather than on
the far side from the pivot point.

Additional to that, with the 2x4 version, you can lock it down much more
securely by building over the plated ends.
