From a Google AI Search Result comparing the 83" B4 to C4.
LG B4 OLED (83-inch model):
Processor:
The 83-inch B4 uses the same α9 Gen7 processor as the C4, unlike the smaller B4 models.
144Hz Refresh Rate:
The 83-inch B4 also supports a 144Hz refresh rate, unlike the smaller B4 models.
Four HDMI 2.1 Ports:
The 83-inch B4 offers four full bandwidth HDMI 2.1 ports for 4K/120Hz gaming, unlike the B3.
Brightness:
While not as bright as the C4, the 83-inch B4 is still bright enough for most viewing environments.
Cost-Effective:
The B4 is generally more affordable than the C4.
In Summary:
For the 83-inch size, the C4 offers slightly better overall performance due to its brightness and processing capabilities. However, the 83-inch B4 is a strong contender, especially since it shares the same processor and 144Hz refresh rate with the C4, and offers a more cost-effective option. If you prioritize the absolute best picture quality and are in a bright room, the C4 is the better choice. If you want a great picture at a more budget-friendly price and don't need the absolute highest brightness, the 83-inch B4 is a great option.

From Perplexity…
"If you have access to both, the OLED83B4AUA offers slightly better future-proofing with Wi-Fi 6E. Otherwise, you can expect identical picture quality, gaming performance, and smart features from either model."
They are notorious for slow shipping. Took 1 month to get a washer and dryer from them
