I'm officialy a helios owner now. Personaly i thought the m8 felt more comfortable to me, but if i were to just put the wheel extension i would say the helios would feel better due to the fact you can turn the wheel in an angle. Also the helios is alot easier to hold and handle. The features on the helios i think is superior, but when it really comes down to racing they are about the same, I feel the helios is alot better.
