Haha I'm the complete opposite. Apart from Batman's main rogues (Joker, Two-Face etc) I really can't say I enjoy many other DC villains. I mean Lex Luthor is just a don and I like Darkseid but other than them I can't really think of any others that stick out in my mind.
Whereas with Marvel I get to read about guys like Doctor Doom, Mephisto, Magneto (Magneto: Testament is my favourite graphic novel that I've read recently), Loki, the Red Skull, Baron Zemo, Green Goblin, the Jackal, Thanos, Galactus, the Hellfire Club and the Kingpin.
Don't get me wrong, I love super-villains across the board and you've listed some killers.
I'll counter with a list of my fav DC villains.
Deadshot, Deathstroke, Eclipso, Captain Cold, Joker, Darkseid, Fatal Five, Boomerbutt, Black Manta, Enchantress, Poison Ivy, Harley Quinn, Bane, Mxyzptlk, Bizarro, Zoom, Johnny Sorrow, Black Adam, Mordru, Mirror Master, Killer Frost, Cheshire, Shadow Thief, etc., etc.,.
I could go on and on.
'Who's Who in the DC Universe' was the fist comic series I ever collected from start to finish and it was a companion to 'Crisis On the Infinite Earths' so a lot of my attachment is very personal in nature.
Edit: I'd like to add my favorite comic book cover ever.
