I find Motley to be better songwriters to Def Leppard too. Def Leppard's writing on their last few albums has sucked.

Motley's lyrics aren't what anyone would call "appropriate", but they're interesting. Ever heard about how Nikki wrote songs like Wild Side or Shout At The Devil? Pretty cool stories.

I've never seen anything very special about either of them as songwriters. I have found much of DL's material to be completely over-produced though.
