Choosing the best griddle is a hard task, but it's hard to top a Blackstone. When deciding which griddle was the best for each category, I looked at a lot of features, including the overall size of the cooking surface, the amount of BTUs, the price of the product and various other characteristics.
The "=""> is the best overall because it leads the way in most of these categories I examined. With the features and specifications this griddle has, you can't get a better griddle.
As for the other ones listed, it came down to what I was looking for rather, it was cheapest, best for beginners, best value and most portable. The products selected for each of the categories were selected because, frankly, they were the best fit for that category after looking at the specs.
