Federal law enforcement question-ICE vs DEA?

Which agency has more "field action" compared to desk time. And how exciting is that action? Do either of these agencies have to be "on-call" at all? Also do they have to travel somewhere unexpectedly? In your opinion, which agency would you rather work for? And for the agency you choose, what would be the best area to work at? Also for ICE what would be the best division to work for too.(financial crime, cyber crime, narcotics, etc.). Any other info on them would be greatly appreciated. Thanks!
