To me it doesn't much matter. I have a slight preference for the "T-bar" design aluminum stakes. I have a couple of the wire designs that somebody lost.

The weight savings of one or another design seem trivial. The wires go into stoney ground easier, but the "T"s are more secure.

When the ground is frozen and there is little or no snow, stakes often don't work well, and rocks or other expedients are required. Same thing, for different reasons, in loose beach sand. Sometimes a fairly long, stout stick, laid horizontally, can be stabilized with rocks.

In snow, relatively large sticks work better for me than any stakes. Bury them horizontally. Disturbed snow will magically harden. I've also relied on cookware. A Sierra cup works well. I hear some use stuffsacks, or plastic shopping bags filled with snow.. Beware of melt-out during warm sunny days.
