Granted, you lose a small % of the pic with the roundies, but I don't even think it was really noticed much in it's day.

Longevity huh? If it's shelf life they are probably all comparable. If it is power it up for as many hours as it takes to burn the cathode off the gun Zenith Delta gun rectangular sets from 1970-78 (chromacolor black matrix era) probably take the prize. The CCII chassis that drove them were nearly immortal too. Some of those sets were found by fire fighters after house fires with the plastic melted and speaker cones burned out still showing a perfect picture under the soot stuck to the screen. Many still work as found today and some of those were in continuous service since new.
