Above all being said, one can achive good results with both bio and non-bio on average if one knows what one is doing.
Large raison d'etre for bio detergents is to work at lower wash temps. OTOH non-bio likely will give better results if one keeps to old ways of using plenty of hot or near boiling water wash temps.
As have said, British hospital laundries well into 1970's got blood out of things with nothing more than soap, sodium metasilicate, perborate bleach and hot to very water. Not an enzyme in sight...
