P80 probably. The P80s single engine was more then both of the ME262s combined. The P80 is faster, Has a higher surface ceiling, has a higher rate of climb, a better weight to thrust ratio, and turned better. Really the ONLY advantage the 262 has is the cannons. Although the P80 still has 6 .50 cals, so its not like its flawed.
