Last week's riveting Lost premiere brought the Jack-Locke conflict to an entirely new level. This time, all of the survivors (including some of the Others) were forced to choose sides. It wasn't an easy decision, and there were some surprising choices. Each side has its benefits and its drawbacks. Let's take a closer look at these new teams!

Team Jack
Pros

• Possibility of rescue: We know that at least Jack and Kate make it back to civilization. Anyone who went with Team Jack has a decent chance of being one of the remaining members of the Oceanic Six. This faction is definitely the best choice for someone looking to get off the island. Sure, Hurley leaves the island, but he might be a special case.
• Contact with the outside world: Naomi brought news from the outside world as well as a satellite phone. At the end of season three, the 815 survivors learned that the plane wreckage had been found (supposedly) and that they were all declared dead. The freighties can catch them up on what else they've missed since the crash.
• An all-star lineup: Most of the island's A-Team stayed with Jack--Sayid, Kate, Desmond, etc. Juliet is also on hand to provide insider information about the island. These are people that know how to get things done. Fortunately, they're also as smart as they are cautious. Team Jack will be sizing up the freighties every step of the way.

Cons

• What happens to the rest of the team?: Sadly, there isn't room for everyone back on the mainland. As far as we know, only six of the 815 survivors make it off the island. What happens to the Team Jack members who don't get rescued? Are they harmed by the freighties? Stuck on the island? Contact with the freighties isn't a guarantee of rescue. Somehow the herd will be thinned.
• The freighties are not what they seem: Naomi was carrying a photo of Desmond, but Penny did not send her to the island. Since the world believed the 815ers were dead, the freighties aren't here for them. Why did they come to the island? Do the survivors fit in to their plans, or are they in the freighties' way? At this point, all we know about the freighties is that they are liars. Not a good start.
• Rescue does not equal happiness: The flash-forwards have painted a bleak picture of the survivors' future. Hurley's regrets about leaving the island drove him crazy, and Jack's life deteriorated some time after that. The Oceanic Six are bound by a dark secret, so maybe getting rescued isn't all it's cracked up to be.

Team Locke
Pros

• Safety: If Ben's fears come true, Team Locke is right to hide from the freighties. The island's newest visitors could end up killing anyone that they encounter, including some of the members of Team Jack. Locke is a little out there, but his instincts are fairly good (on the island, at least). Team Locke is the perfect place for those who want to remain on the island and those who are suspicious of the freighties.
• Island answers: Locke is all about uncovering the island's secrets. Ben appears to know more about the island than anyone else. Team Locke is the survivors' best chance to learn about a whole mess of island mysteries.
• Better accommodations: While Team Jack stayed on the beach, Team Locke set out for the Barracks. The Others' former home is full of modern conveniences. Even the opportunity to live indoors is an improvement on the beach tents. Life with Locke will be much more comfortable.

Cons

• Ben can't be trusted: Ben is still technically a prisoner, so you know he's going to manipulate the 815ers and try to escape. He willingly joined Team Locke, but he could make another attempt on John's life (and hurt others in the process). If there's a weak link the group, Ben is sure to exploit it. The survivors will have to be careful around him.
• Locke has his own agenda: Unlike Jack, Locke doesn't act out of concern for others. He's motivated by his own mystical relationship with the island. Remember when he described Boone's death as "the sacrifice that the island demanded"? Would you follow a man who sees you as a means to an end?
• Hurley regretted going with Locke: In his flash-forward, Hurley told Jack that going with Locke was a mistake. That statement doesn't bode well for the members of Team Locke. Will John betray his fellow survivors or leave them to fend for themselves? Will Ben gain the advantage and take control of the group? Both men are dangerous in moments of desperation.

Which team do you think will have the best fate?
