Why would putrafacation (decomposing of animal foods) smell better than fermentation of carbohydrates? Makes no sense.
My observation is our gas smells better. Maybe others would like to weight in.
The other thing to consider is you have something else wrong - like bleeding in the bowels produces foul smells.

Could the problem be one of nutrient density?
Table III of
this old study on the sulfur content of various foods lists 100 g of raw steak as having 203 mg of sulfur, and 100 g of boiled spinach as having 86.5 mg. However, when I look up the calories, I find that 100 g of lean
strip steak has 117 calories, while 100 g of
boiled spinach has 23 calories. When adjusted for equivalent calories, the spinach has 440 mg of sulfur to the steak's 117 mg.
So, if "[t]he offensive odors of flatus are caused by tiny amounts of sulfur-containing gases" as you say in a
2002 newsletter, wouldn't it not only be possible, but even plausible that some people would have worse gas on a vegan diet?
I have the worst gas on this diet than I have had eating any other way, although I have never tried any low-carb style diets for comparison.
