Fouling is a function of at least two issues.
1. How naturally dirty a particular brand of powder is,
2. Speed of your powder burn relative to crimp
If you notice lots of fouling streaked down the side of casings (particularly pistol cases), than you need to crimp a little more (being mindful of pressure considerations)for that particular bullet and powder matchup. That will help you powder burn more completely. I would say that in general faster powders may tend to be a little cleaner as there is usually a lighter load of fast powder.
