The kennelsol is more of a cheaper solution used for general purposes, easily dilutable and leaves a pleasant scent.
The ygiene would be used more for examination tables, medical tools, grooming supplies etc. as its somewhat expensive and not highly dilutable.
Ygienes main selling point is that it is a new level of 100 percent effectiveness against all microorganisms in a very short period of time.
Anything mission critical to actually kill all microorganisms is where it shines.
And for surfaces heavily soiled with fungi etc like decks because its power to cut through mold and kill it is also unheard of.
The main advantage quats like that kennelsol or lysol have is that the concentrate is insanely cheap and can be watered down to enormous amounts.
