It is just as good. Cowboy charcoal or Royal oak charcoal... or any charcoal that is just 100% hardwood.
The Bio-Char is excellent for long term nutrient release and I love it in my no till containers. It's like a Microbe condo.
As bughunter said, the key is to pre-charge the crushed up charcoal to make sure that you don't rob the soil of nitrogen of other nutrients while it soaks up in your soil.
Crush it, soak it in compost tea or fish emulsion for 3 days or longer and you'll have an amazing product for any type of gardening, from small container to large acreage.
Bonus is that is will also act as an aeration amendment at the same time.
