Strongest Character The Darkness Can Beat?

I've heard a lot of different opinions and facts on The Darkness's power level, so I'm just wondering, who is the strongest being The Darkness (Jackie Estacado) can beat?

I mean, he's knocked Superman around before, so I'm just sorta confused on his ranking in power.

IMO it all depends on jackie himself. Giving the right motive he can be top of the pile so to speak.

@crimsonlord53: By this I mean if Jackie were willing to kill the person he is fighting.
