Short video comparison of the two headsets. My personal favorite: the Game One.
Why I chose the Sennheisers:
Extremely comfortable. Perfect audio. Perfect mic (easily the best on a gaming headset I've ever used).
The open back of the Sennheisers allows good airflow to keep your ears cool. The cushions and weight of the headset make it perfect for long gaming sessions. However, if you need a closed back due to noisy areas headset, take a look at the Revolver S or the Game Zero.
