Panko breadcrumbs are flakier than regular breadcrumbs. They're coarser and yet lighter. They're made from white bread that's had the crust removed, so they end up crispier when toasted or baked. You can look for regular Japanese panko made with white bread. You can also use whole wheat Panko or gluten free, or if you're looking for a keto friendly or paleo option, you can find Panko crumbs made from dried pork rinds. As for what is best, it's all up to you and what you like!
