To Band, or To Hero

• Opinion1: musicians and experienced rhythm game fans will likely prefer the innovations of "Guitar Hero: World Tour," while “Rock Band 2” will appeal to casual players and online gamers for its ease of use and proven experience.
  Rabid music fans will likely want both of these games for a maximum number of songs, and this is the best way to do it: "World Tour" has the best instruments, and both games are compatible with the other's peripherals. So buy the complete band pack of “Guitar Hero: World Tour” for $190 (a second guitar controller and mic stand costs extra), then drop $50-60 on the stand-alone “Rock Band 2” disc for more song fun.
  
  
  
  'World Tour' pros:
  
  • Improved instruments
  • More aggressive track list
  • Better tablature makes you feel like more of a rock star
  
  'Rock Band 2' pros:
  
  • Better band chemistry makes you feel like a group
  • Easier setup, no buggy hardware
  • Unmatched online play
  
  
• Opinion2:
  In a perfect world I would recommend going with the Xbox 360 version of the game...
  Rock Band is sort of for more experience music gamers ... and are into cooperative online gameplay.


• Opinion3:
  There's a fundamental difference in the ways Guitar Hero World Tour and Rock Band 2 play out: One punishes you, while the other is all about the music. Let me explain.
  
  Rock Band 2: If you were to buy the game, plug everything in, and throw a party, you'd have all of the songs waiting for you and ready to roll. If you plan on hosting a few of your less-talented buddies, you can resort to No-Fail Mode, which lets everyone blast away regardless of how off-key the playing is. In short, though plenty of challenges are available for the serious gamer, you can also flip a switch and just have fun.
  
  Guitar Hero World Tour: With this game you need to unlock all of the songs you want to hear. So, if you plan to throw a Guitar Hero party at your house, you'll need to make sure to hold a marathon jam session ahead of time to unlock all of the songs. {...}
