It seems like the debate has been echoing around the Twi-verse forever, and it's definitely not going to quiet down once "New Moon" arrives in theaters: Are you on Team Edward or Team Jacob? Do you fancy the smoldering teen vampire or the buff teen werewolf? Who should Bella Swan choose?

And, of course, you must choose! That goes for folks in the "Twilight" fanbase and the castmembers themselves. Everyone has to wade into this heated debate about supernatural, amorous longing.

Ms. Bella Swan herself, Kristen Stewart, views the choice between the vampire and the werewolf as one that pits your head against your heart. "For whatever reason, Bella is instinctually in need — I mean, can't live without Edward," she explained in an interview provided by studio Summit Entertainment. "So if I had something like that, that definitely would be what I went for because I wouldn't have a choice."

Yet Stewart said that while Edward has captured Bella's heart, the "Twilight" teen knows Jacob would ultimately cause her less pain. "Objectively, from the outside, she should be with Jacob," Stewart said. "She's best friends with him, he's warm, it's easy, there's no problems there. But you can't always take the easy way. "

The easy way or the hard way? Making that call, Taylor Lautner said, depends on what type of person you are. "Team Jacob. If you believe in that friendship and you guys are friends at first and you develop this deep friendship, then all of a sudden fall in love later on, then you should be Team Jacob," he said, stumping for his character. "Come to the dark side! But if you believe in love at first sight and seeing that mysterious man in the corner, then all right, join Team Edward."

What does Robert Pattinson think? To the man behind Edward Cullen, it's not about going with your heart or you head, and it's not about choosing friendship over mystery. For RPattz, the important distinction between the two characters — and the key to deciding whose team you should be on — comes down to whether you want to go through life riddled with anxiety or be able to live in the moment.

"In really simple terms, Edward is much more of a worrier — not a warrior but a worrier — and Jacob isn't," Pattinson said. "And that's the biggest difference between them."
