The God among Insects. In Power Company, a powered up Dr. Polaris was ably to effectively keep Superman at bay with cascading forcefield walls. Mags could just put the Hormonal Duo in bubbles.

Superboy also promptly died in that comic.......Wearing an S shield. These things have to be taken into consideration. Same guy who was bloodied from SB laughed off BA's attacks. Inconsistent maybe. Or a good showing in death??
Magneto wins and looking at both SB Vs SBP fights, Conner got in one hit and a tackle which promptly killed him. I wouldn't say they went head to head.
However, it's interesting that Nightwing survived the tower explosion seemingly unscathed.
