[40K] Which species treats its citizens best?

Depends on how you judge it. 
If you judge best treatment as what the peoples of the society desire, then I'd hands down call it a tie between Orks and Tyranids. Perhaps leaning towards the Orks because they don't suffer the same unfortunate food shortage and long journeys between galaxies.
The Orks only want a good fight, lots of dakka and plenty of teef and loot.
