crew size in gta 6 online: 4 reliable people or 40 for coverage?

I've been thinking about this a lot since pre-orders opened. My best GTA Online crew was never more than 5 people. We all knew each other's schedules, and if someone couldn't make it, we'd just run contact missions or mess around. The few times I joined a 30+ person crew, it felt like a ghost town in the actual session. Someone was always online, sure, but they were scattered across different lobbies, and the crew chat was just noise.

I'm probably biased because I love testing heist edge cases. With a small crew, you can coordinate weird physics experiments without randoms blowing you up. I remember trying to wedge a car into the Pacific Standard bank vault with 3 friends, and we spent an hour just seeing if the collision would glitch. A big crew would've had someone impatiently starting the finale.

But maybe GTA 6's netcode will handle large crews better? I doubt it, though. The more players in a session, the more desync and odd vehicle behavior I've seen. I'm curious if anyone's had a large crew that actually functioned as a tight unit. What's the weirdest crew-related glitch you've seen that made you rethink your crew size?
