Glass - Porcelain comparisons:

Glass

Higher dielectric strength (~140 kV/cm vs ~60 kV/cm)

Better performance in contamination (smooth surface sheds dirt)

Utilities prefer glass today

Porcelain

Still very good electrically (industry standard for 100+ years)

More prone to contamination buildup (needs coatings/cleaning)
