Orbit and Pickup are two different videos
Orbit style gives every fighter a permanent weapon circling them. Damage is a function of where the two fighters are relative to each other and where their weapons happen to be in their orbits. The fight is continuous, and the whole match is legible as a single ongoing exchange.
Pickup style removes the weapon and makes acquiring one the central problem. Fighters begin harmless, weapons appear at random points, and the first to arrive gets it. Because weapons are consumed, no advantage lasts, and the match becomes a sequence of short armed windows separated by scrambles.
Neither is better, but they suit different lengths. Orbit reads well over a longer run because the state is always clear. Pickup is better short, because the constant reset in advantage keeps the first thirty seconds dense with reversals.
