People who say she plays like Jazz don't know about her sick sidekick glitches (or streetfight). I consider her to be better in MP than SP. Sure you can kill enemies easily with her sidekick, but I'd rather shoot them for pickups. But being able to use sidekick against powerups super fast is pretty useful in the fast paced MP, as it grants you full ammo.

You can actually reach half a tile higher than uppercut by using golden jump, which everyone can do. Unfortunately it's not the best substitute for uppercut since it forces you to the left/right and takes a while to charge up.

She's also generally better for speedrunning than Jazz, but who cares about those?
