Best Rocket Armament of WWII?

[Monkeyfume]

What was the best aircraft-mounted rocket system produced in WWII?
Although it could take quite a few shells to take down a fighter, attack plane, and especially a bomber, in most cases the same could be done with a single rocket.

Which rocket had the highest velocity, hit ratio, explosive power, that would make it the choice weapon of a pilot who had options.

Doesn't need to be produced in significant numbers, just at least a few built before the end of the war and proven themselves in tests.

I'm guessing they were all much the same in their effectiveness and, more importantly, in their accuracy. Very inaccurate, and in the main, a waste of time and pilots.

There were only 3 air to air "systems" used in WW II although any air to ground rocket could be fired in the direction of an enemy aircraft. Leaving out that category Leaves you with the Russian RS-82

and the German Werfer-Granate 21

Which was only really useful against formations, not single aircraft and then the R4M rocket.

Used at the very end of the war.

Hit ratios of all were pretty dismal which required firing in large numbers.

Folding fin rockets are far superior to other unguided aircraft rockets. Did anyone besides Germany field a such a weapon before the end of WWII?

Without being more specific as to how folding fin weapons are far superior to other unguided aircraft rockets, this is a hard to quantify claim to make: on what data is this claim justified? In regard to the R4M, is there any evidence to suggest it was any more accurate than any other unguided air-air rocket of a similar vintage?
