[Profiler (Profiler)]

With respect to objective coatings there are clear differences in the brands epecially with respect to their durability to such things as sky gunk requiring cleaning, moisture damage/erosion and general longevity.

Ironically, the best example I have personally been able to observe of this point in the short term was with two diagonals (a GSO and TV Everbrite) I purchased at roughly the same time.

Initially, I was immensely, immensely impressed with the GSO providing great performance for an absolutely magic price and disappointed with the Everbrite being super expensive and not really any different to the GSO.

To-day, now roughly three years later however I can see deterioration of the coatings creeping in all around the edges of the GSO mirror - the Everbrite is exactly the same so rather than puffs of smoke and bravado I can accept the TV marketing as not merely hyperbole and their products in the context of life time investment etc.
