I took mine with a breaker bar. See if you get a friend to hold the socket in while you handle the breaker bar. Less possibility of stripping. You can also try some heat with a torch.

They usually freeze up when cold - it's best to remove the HEGO when it's warm. Idle the engine, or just heat the bung up with a torch. That should loosen it.

(I'll usually remove a HEGO after a short drive, for that very reason.)
