Weapons and damage of them are just luck of the draw. Color of them doesn't matter on how good they are, usually. My level 50 white wakizashis are the best weapons I have, just as good as my Zed's Demise.
As for the devastating home run, I'm not too sure about that. The kind of bat you used shouldn't affect the special hit rate. If you are looking for the bat that electrocutes enemies near 100% of the time, that is the Developer Mod Home Run Bat.
