If you are a rec diver using AL80s at mid level depths, you are probably going to use up your gas before you get to your NDL using nitrox.
So if your dive time would be the same, whether you are on air or nitrox, your nitrogen load would be less using nitrox.
Even if the DCS incidence is not that different, the incidence of venous bubbles is higher when using air.
Enriched Air Nitrox Breathing Reduces Venous Gas Bubbles after Simulated SCUBA Diving: A Double-Blind Cross-Over Randomized Trial
I prefer to not have bubbles in my blood, so I'll stick to using nitrox as much I can.
If you don't want bubbles in your blood stop SCUBA diving and take up free diving. You get bubbles in your blood with or without nitrox.
