I don't agree with generalities.
Except that, in general, stick powders produce tighter groups for competitive shooters than ball powders. (has to do with the powder/primer interface consistency, which is a whole nother post...)
I have notice no difference in fouling, at least not between two powders that have similar burn rates, like IMR4064 and Power Pro 2000 MR.
