The C2 is a fine TV. Unless the Bestbuy guys have had both sets in their homes, I don't think they can really say either way regarding the G3. The C2 to C3 isn't a big move and isn't a move I'd make myself. But, somebody may just want DTS and 48Gbps. The G3 is currently the best featured and brightest OLED TV on the market with brightness levels substantially better than any other LG models. But, it is very expensive and many may need a new TV now and be looking for deals on last year's model. This is what I did with my C1 last year. All 77" C1 TVs had the EVO panel and the C2 didn't bring back DTS or 48Gbps bandwidth support so I would not have gained anything I could not live without. If I'd known what the G3 was going to offer this year, I may have waited and saved for it. But, I do not regret buying my C1. I wanted to experiment with next gen game consoles on an OLED TV and also wanted the perfect blacks that cannot be had on an LED set.
For those with no need for 4K @120Hz and certain HDMI 2.1 video features who only use their TVs as monitors with their devices connected directly to their AVRs, I see no reason not to consider the A2 for a considerable savings over the C2. The savings could be applied to the G3 next year when the 4 models come in and the A2 can go into another room or sold to help pay for a G3 if somebody wants the fully featured and considerably brighter model. None of the LG OLED TVs deliver a picture anybody can call less than amazing. Lighting and placement conditions in the home will vary of course.
The LG C2 OLED is a higher-end TV than the LG A2 OLED and has better performance and features. The C2 gets much brighter, especially in HDR, so highlights pop more. If you're a gamer, it's better to go for the C2 as it has HDMI 2.1 bandwidth and VRR support, which the A2 doesn't have, so it...
