I'm also deciding between these two only. Went to a couple of showrooms this week but they only had C2 and A80K.
AFAIK,
G2:
- Better blacks in ambient light due to polarizer on the screen. QD-OLEDs look purple/grey.
- In bright white scenes it's the brightest TV around.
- 4 HDMI 2.1 ports v/s 2 on the Sony
- G-sync, freesync and proper HGIG for a better gaming experience.
- Dolby Vision at 4k 120Hz. Also, LG usually does tone-map Dolby Vision the best and has least bugs
- Cheaper by about 1 lakh rupees
- Has a 55" option if you just need something personal for the bedroom for cheap.
A95K:
- Higher colour luminance
- Higher colour gamut
- Should be more resistant to burn-in, theoretically
- Overall higher PQ and Sony's processing
- Better sound
- Support of DTS codec
I usually go back and forth between them. But considering the major price difference, if the PQ difference isn't that large I'll go with the G2. Will upgrade in 4-5 years when QD-OLED will be available in 77" and will have better polarization.
I'm mostly shifting to Bangalore next month too (in the midst of a job switch). Would love to go and check out the TVs side by side and negotiate.
