Fusion 500 vs Delta

[Aelerium]

Hello.
I'm going to buy a cable headset of Asus ROG series for gaming only, but unfortunately I haven't enough money for the best option — Theta 7.1.
So I have to make a choice between Fusion 500 and Delta.

Asus ROG Strix Fusion 500 has only the ESS 9018 DAC and ESS 9601 amplifier (when Delta has got the 4x ESS 9218). And a sensor panel for volume adjustment doesn't look a reliable solution for me.
Asus ROG Delta seems to has no 7.1 virtual surround sound (is it really important for a gaming headset?) and has weak earshells' bracings. People also report it to suit well neither for a big head, nor for a small one.

Which of them should I buy?
Or maybe there is another option (for example, such wireless headsets as Fusion 700, Go 2.4, etc.), even if I'm going to use it only at my PC?
