I think the headliner utility and longevity issues depend a lot on the knowledge and experience of the manufacturer and the subsequent selection of quality materials being installed in the proper manner.
Some less experienced manufacturers or boat owners using these type of materials, especially of inferior grade, will get mixed, sometimes poor, results.
The headliner on my Sea Ray is at least 3/4" thick, and composed of multiple layers of various materials designed to insulate and breathe, and has never shown any condensation or mold/mildew. The whole boat shows experience and quality in construction and materials, and after 20 years, shows very little wear and deterioration inside and outside.
