Which is better for a bright living room?

The C5 bundle. It has an anti-glare coating and a brighter OLED evo panel. The B6E lists no anti-glare treatment, so window glare will show more.

Which is better for gaming?

The B6E on features: G-Sync, FreeSync Premium and a 0.1ms response time. The C5 wins on size and a 144Hz panel, which matters if you have a PC that can drive it.

Is the 77-inch worth the extra money?

At $899.00 for the C5 bundle against $799.99 for the B6E, the gap is about $100 for 22 more inches. That is the better value if your room fits it.

Which has better HDR?

The B6E, because it supports Dolby Vision. The C5 bundle lists HDR10 and HLG only, so Dolby Vision discs and streams will fall back to HDR10.

Neither has a published panel lifespan. The C5 bundle includes Allstate protection for 5 years total coverage, which the B6E listing does not.

Do I need a soundbar with either?

The B6E supports Dolby Atmos, so it does more out of the box. The C5 has Precision Sound Master Pro virtual surround, but a soundbar still helps on a 77-inch set.
