Which Game is Better?

[Wii_Master]

As the title says, which game of the two is better. I am getting one of them for christmas but don't know which one yet. I am leaning towards Beatles Rock Band because its $70 cheaper.

 

I wanted the game with a very good career/story mode and also with lots of songs and have online. I am pretty sure that both have online though.

 

Also for the online, what do you do in online? Like do you play songs with others in like a band (the other person plays guita and i play drums) like that or do u just trade songs and extra stuff like that?
