If I could have purchased the LG G3 77" around Black Friday timeframe last year for cheaper than the Samsung I absolutely would have. I really wanted to go with the G3, but was around a $1,200 difference that was hard to justify for the bump in quality.
At least a few years ago, it was cheaper for me to buy an 55" LG OLED TV than a comparable Samsung model in the US, and that was factoring in the Samsung employee discount I had at the time.
