If you are looking for a more cost-effective option and mostly watch movies or play video games in a darker environment, the LG B3 would be a suitable pick. However, if you prefer enhanced audio quality, a brighter picture for daytime viewing, and a slightly better overall picture quality, the Sony A80K might be worth the extra expense. The Sony A80K also offers a bit more versatility with stand positioning which could be beneficial if you have a space constraint or plan to use a soundbar. Keep in mind that the LG B3 is a newer model, but the Sony A80K, despite being older, manages to hold a premium position with its features. Give Feedback

USA Today
Michael Desjardin | December 2022
"It’s a high-end TV through and through something that becomes clear the moment you glance at its stunning picture. The A80K’s surgically precise contrast control is likely the first thing you’ll notice about its picture ... every piece of content looks better when this amount of precision is available. Color accuracy is another strong suit; the A80K features fantastic out-of-the-box color accuracy in the Custom picture mode."
