80s Magnavox vs. Sylvania. Any difference?

[waltchan]

What's the difference between Magnavox and Sylvania when Philips made them back in the 80s? Was Magnavox considered to be a higher-end version of Sylvania, or was Sylvania higher-end than Magnavox? Were Sylvania CRTs from the 80s any good and have you seen one? I read a lot of threads here already, but I don't hear anyone mentioning Sylvania too often here.
