The chemical form describes more than the brand name

NIH ODS identifies thiamin hydrochloride and thiamin mononitrate as commonly used stable forms. It distinguishes benfotiamine as a derivative that is not water soluble. [1]

Those differences help identify the ingredient. They do not establish a universal ranking for every nutritional or clinical purpose. [1]

The intended use determines the relevant evidence

Routine nutritional intake, treatment of a diagnosed deficiency and a study of a particular disease are different contexts. Compare evidence for the actual preparation and purpose rather than choosing solely by an absorption claim. [1]

A more elaborate ingredient name does not itself establish superior symptom relief. A prescribed treatment should not be substituted with a retail derivative without checking the clinical plan. [1]

Match the formulation to the question

Imagine a trial studies benfotiamine for a specific condition. That does not demonstrate that every person seeking routine B1 intake should prefer it to mononitrate or hydrochloride.
