p228 vs colt

I searched it and only found about 5 threads that really didn't answer anything.

Are they both 1HKO in the head? I know Colt is.
Which would be better for m700?
Which would be better for ak47?
I saw that p228 has a faster firing rate, but I played with a colt and it seemed like colt is faster AND stronger.

Thanks~
