Well I guess I'm the outlier here. I've owned Samsung TV's and Sony's mostly, which I prefer but are on average 25% more expensive than their competitors, and none have failed to date. I and the missus also have their smartphone's and low end audio products (DVD player, radio's), a fridge, around the house and knock on wood, nary a problem with any of them.
The few times I've had to contact their tech support, smartphone features related, they've been very responsive and more importantly, honest. Admitting that the latest software/firmware upgrade has issues and it was being addressed, and soon thereafter it was, which I appreciate.
We also just purchased a 49" Q6F series OLED last year and the picture quality is fantastic, compared to the old 55" LED in the living room. I feel like I got my money's worth and they're reliable. I'll probably replace the 55" Samsung LED whenever it fails with another Samsung TV more than likely, if it ever fails at all.
Would I prefer a Sony? Sure. They're just to damn expensive and their optional features (streaming, Netflix closed captioning, etc.) always seem to be a year or two behind their competitors.
Just my .02 cents.
