I agree with the Bibi but she gains more from the boost than the actual effect. I'm not the biggest fan of Bibi personally but if I played her more I might have moved her up a few spots
bibis HC is better since u can get teamwipes, turn the tides in a match, and cycle supers easily. combine it with healing gadget cordelius HC is a add-on, he can do well without it and he cant teamwipe. the stats are good tho primos HC is just like cordelius, its a add on but he do teamwipes and cycle supers. buzz HC is decent, u might get teamwipes but he can just guarantee a kill like cord, his HC trait is lame ive seen players waste HC trying to do it. overall bibis HC makes her really good from a bad brawler so its the better one.
