Darius or Kog'Maw?
Split between getting one of these champions. Who do you guys think i should get?

If you want simple easy wins play Darius.
Kog'maw is harder to play and died easily if played wrong
I'd choose Darius.
The Tank update hit Kog with a whole slew of indirect nerfs. He's not bad by any means, but he's been pulled down into 'reasonable' territory.
Darius is still really strong and much more forgiving to play.
