Lately, Royal Oak, before that Maple Leaf, soon Basques Sugar Maple briquettes. Have tried the Weber, but I can't justify the price.
IMO, Kingsford because of all the additives is a no go for me, plus we never have it on sale.
On a scale of 1 to 10, I would probably give KBB a 7, all the other briq's I have available, I would score above 9.
