One-on-one, it's not even close. The Me-262 is probably the only thing that can out-run it, and it's cannon could shred anything that moves.
However, if you are talking about impact, you have to consider logistical matters, and the support structure for the A-10 didn't even exist back then.
Einstein got it backward: one cannot prevent a war without preparing for it.

The gun would be absurd overkill considering one HE 30mm round would destroy pretty much any fighter.
Do you mean "isn't terribly fast" as in "not that much faster than everything else", because even the P-51 is slower.
