Pedantic response: In C#, I find "binary serialization" much easier to program with than JSON. Then again, the resulting blobs require specialized tooling to read, and they're very hard to work with in other programming languages. --- But, jokes aside: I find CSV is great for "rows" because it doesn't repeat field names for every object. I really like XML when each tag is an object, and fields are attributes. Most people don't understand this and end up making a hug mess; and some serializers do this by default too. IMO, this is why JSON became much more popular.
