I don't think it would be possible to make a comparison. The round nose usually have more lead exposed and the spitzers are usually designed for higher velocities.

But for short range use and moderate velocities the round nose certainly are consistent. The moderate velocity and blunt shape may improve straight line penetration.

I used a lot of RN bullets when i bought in to the brush busting myth. They worked so well I continued to use them even after the myth was busted.
