Perhaps on paper, but for me, personally, it is harder to breathe.
Breathing petrol exhaust isn't exactly pleasant, but you can still more or less breather. With diesel, even perfectly clean/clear diesel, I just feel like I'm not getting any oxygen in my lungs. I've followed many a diesel while riding a motorcycle, even very small displacement diesels, and the sensation is unmistakable (and annoying).
