What case is better and has better ariflow?

Obviously the HAF XM, has better cooling options that's why it's called High Airflow (HAF) and it's a little bit more expensive.
Those cases are very different:
The Scout 2 is designed for LAN party, and that stuff (A "Portable" case with good features)
The HAF XM is more for cooling performance.
