Quick verdict

{name} in short

The best all-round functional filament for most people. Tough, slightly flexible, weather resistant, and food-contact friendly in most formulations. Tends to string and stick too well to smooth beds.

{name} in short

Carbon-fibre PETG: stiff, strong, and still reasonably tough. A good functional material if you have a hardened nozzle.
