Titan Drone or Comet Sampler?

[Macavity]

From a "Tweet" by magazine Astronomy Now:

NASA has narrowed its choices for a new billion-dollar robotic space mission:
A nuclear-powered quadcopter to explore the hazy landscape of Saturn’s largest
moon Titan, or a probe to scoop up a piece of a comet and return it to Earth.

So which would you choose?

Me? I think I would LOVE to see more pictures from Titan, but
perhaps a comet sample provides more "fundamental" research?
2034 for the Titan "Dragonfly"  seems a long way off though... 

Never tried making a Poll, so no idea how this will turn out!

I've voted for the Titan drone, the comet sample will have melted on its return to Earth.
