Flatfiles ingestion on Bronze layer, 'to schema' or 'not to schemarize'?

Hi all, What is the general guideline for handling flatfiles (xml, json with several nested hierarchies that is also schema evolving) in the bronze layer?

Should I persist the file content into a single column as text in the parquet file

or

should I let spark infer a schema and have it output a parquet file with several columns representing the content of the xml/json file?
