Out of curiosity: first high-quality color tv?

[Jon Noring]

I'm not a tv collector, and don't know much about the early sets except remembering watching tv on my aunt's Zenith from the very early 60's and being amazed. So with that backdrop, I'd like to ask a question...

Since the first "modern-era" color tv's were sold in the 1950's, I'm curious as to which brand/model of color tv, sold to consumers, is considered to be the first one to reasonably achieve the level of picture quality that we come to expect in today's typical CRT-based tv's. (We can consider models with the "roundie" picture tube -- it doesn't have to have the more modern rectangular shape we come to expect.)

From perusing various threads it appears the likely candidate would be some higher-end RCA or Zenith model, but of course would like to get the perspectives of the experts here. (I'm also curious if a tube-based model is offered, or if we have to wait for a solid state model.)

Thanks!
