What happens when I try and mix powders... This is why I don't like them...
Pyrogallol is a light, crystalline powder that tends to become airborne. That can be a real problem. Gloves, apron, eye shields, and dust mask are usually called for, since it is a significant dermal and inhalation hazard. Catechol comes as large, solid flakes without dust. It is very easy to measure and mix. It is also not an inhalation hazard and not much of a dermal hazard.
Xtol, and other powders, are pretty easy to mix. A one liter kitchen measuring cup or a 2 liter plastic drink container makes life easier, and you can use plastic or stainless steel mixing utensils. (Devote them to darkroom use only.) The problem with powders is that you have to process enough film to use them up before they expire. That problem also exists with liquid concentrates, but it is easier to manage with them.
