Steel 5H vs Icemat

What one do you think is better using the USB versions. Dont worry about price. Just which one is better quality? Steel 5H or Icemats?

I just recieved the Siberias about 5 minutes ago, and they are amazing. No pressure on the ears, the open ear design doesn't make you feel like sound is bouncing around your head, much like the 5H. However, the pull-out mic on the 5H is a great design, where with the siberias you have to put the mic on your screen or on the headphone cord itself.

Love my Steelsound 5H, I don't have the USB version cause I had my X-Fi when I got em. Sold the X-Fi though, so now it sounds like crap on onboard.
