None of the above. For a tank or two in a days diving, I see no difference so I don't bother with Nitrox for my regular diving. On a three day lobster diving trips I switched to Nitrox because I felt better each evening than when I used air. The dives I make are relatively the same as I'm hunting lobsters, not trying to push NDL. They don't call it geezer gas for nothing.
One thing I noticed in the studies they have a specific definition of fatigue that is not the same as the nebulous definition that us regular folk use. In one study they found there was no difference in fatigue, however the majority subjects noted on one evaluation that they felt better after the Nitrox dives, and perhaps sub clinical DCS was the reason. Since the study was about fatigue, they only noted that there was enough evidence to suggest a study about feeling better and Nitrox.
