C# or Java

Hi,
I want to learn(I already know the basics of both) either C# or Java. But I don't know which. So /prog/ please compare the two language for me. Language features/how well it is designed/etc. are the things which interest me.

A good programmer (not working for some soul-crushing sub-sub-sub-contractor and living in fear of having to train some towelhead replacement next week) might go his entire career without seeing anything except Oracle DB or Peoplesoft. They run like Cisco in that it is sold along side expensive service contracts where they do everything for you.
