I'll have to check on whether the Kaneko Sword (P) is also "deals 150% attack" rather than what the tooltip of "Attack is increased by 150% when equipped by Uesugi Kenshin" says. I have one of those now as well, but need to level it up a ways for a cleaner comparison with existing gear.
If both weapons are really a 50% damage boost, not 150%, then that's a lot less interesting, in part because you have to use a not overly strong general to get the boost. Kaneko Sword should still be quite good for the effect of attacking an extra target, assuming that that isn't also restricted to Uesugi Kenshin and possibly Dragon of Echigo.
By the way, the character card that the sixth opponent can drop is a medium soul card, not a general or EVO card. I'm guessing that the cards that some other opponents drop is also a medium soul card.
