Anyone knows in what situations this approach is superior to jsonformer (https://github.com/1rgs/jsonformer https://github.com/1rgs/jsonformer) and vice versa?

Anyone knows in what situations this approach is superior to jsonformer (https://github.com/1rgs/jsonformer https://github.com/1rgs/jsonformer) and vice versa? Or are they solving different problems? It seems jsonformer has some advantages such as only generating tokens for the values and not the structure of the JSON. But this project seems to have more of a closed feedback loop prompt the model to do the right thing.
