My assessment : I would pick the 1st diamond as the ranking of inclusions are cloud, crystal and then feather since cloud is the least obvious, followed by crystal and lastly by feather. Furthermore, the last diamond has 3 long feathers and the second diamond has several shorter feathers (though at the girdles), the possibility of having obvious inclusions using one's naked eyes would increase.
You would have to look at them and see which one looks cleaner to your eye. Everyone has a different perspective, but just by looking at the pictures I would pick the second.
If there is not much contrast of the crystal in the center of the third stone I would go for that one instead. But if they are all SI2 they should look more less the same to your eye otherwise they would not get the same clarity grade.
