I thought you could only get the true ending from beating Survivor. I have yet to do it though, so I can't confirm personally. I was fairly certain I saw it somewhere, though it could have just been rubbish news.
I don't think it matters. What I read was:
Best Ending: Retrieve the Panacea and board the helicopter.
Good Ending: Board the helicopter without the Panacea.
Worst Ending: Die trying to reach the helicopter.
Good Ending: Board the helicopter without the Panacea.
Worst Ending: Die trying to reach the helicopter.
All 3 are actually pretty similar, too.
