Which are to be preferred in the kind of CO2 guns that use eight shot rotary magazines?

Not just the Umarex classics, but also in blowback guns like the Sig 250 and 226, Beretta PX4, CZ75 P09 Duty and the Gamo guns.

Which type of pellet is better designed for jumping from the mag to the breech?

Or is there no real difference?

As always I would appreciate your advice.
