Neither of my B&B or ikairi2 got extra power. I put Def 3 on B&B and Second Chance on ikairi2.
I'll admit that Second Chance did help during HSC with the gummi copter mobs, but once that saved me once, DB3 each time prevented the copter mob attacks afterwards.
That said, having both of those on the same keyblade is quite handy.
