talc vs starch vs cellulose as foot powder?

I’ve seen various starches, talc, and cellulose with talc, all as a base in foot powders.

How do they all compare?
There must be differences in absorbancy, smoothness, PH, or something that would make some better than others.

I know they are phasing talc out but I like it the best. I use starch but not as big of a fan.

I’ve used Gold Bond (talc) a few times and always disliked the gritty feel it seemed to have. I don’t know if it was the talc or something else, but not my fave.
I currently use Desenex (cornstarch) on my feet and it doesn’t feel gritty at all. Plus the Desenex seems to be more absorbent than Gold Bond ever was.

sorry, I guess that wasn’t a very GQ answer
