BEST Aircraft Gun/Cannon…

Hello all, i’m not sure if anyone ask this before, but anyways, i think the 25mm version of the GE gatling gun used on the AV-8B is the best guns since it is not too small in caliber (bigger than Vulcan) while being compact enough to carry enough rounds in small spaces, and SPITs enough bullet into anyone moving across its crosshair(this gun should be used on the F22 instead)…I heard the Russian claimed their 30mm cannon as being the best…while the French Mirage has been using the same gun for ages (just like M60)..how did IDF ranked the guns since they used it more in ACM than any others…and they used all types, including 30mm on Skyhawks(i think its 30mm, not sure) and 20mm cannons on older planes from the US, and 20mm gatlings…and the guns from the Mirages…
