Please enlighten us as to the source of information that leads you to believe that ALL Panasonic TV's are a Vestel re badge. "Panasonic - some LED TVs sets from Panasonic, such as the A300, CX350 and CX400, are made by Vestel, these are mainly entry level/budget, 'HD-ready', HD and some low cost Ultra HD 4K models (for example, the CX400 series)." https://en.wikipedia.org/wiki/Vestel
OK, so 1) not the Toshiba but the one posted and the two you mentioned, and 2) I was talking about panels specifically as that's the thing most people are concerned about for Vestel. But fair point. :)
Just to clarify, in case you're not aware, all 55" panels are LG, and none are Vestel rebadges. So basically, your choice on panel is LG, LG or LG. Or, in the case of the new Toshibas, LG. The rest is processing, and none of them are terrible. Buy away, free of your Vestel vexation!
Thanks for the info Brownbloke. Bought my LG C6 a few years ago now and they have been good regarding updates. (Even if one of the updates made the HDR game mode dull.) Its a horrible feeling when you've bought a flagship and the manufacturer dumps support, (especially if there are still issues.)
