Wireworld Aurora/Stratus

Hello all, I am looking to make a modest investment in power cords over the stock cords to power amps. I have been looing at the Shunyata Venom 3 which has gotten great reviews and feedback, and Wireworld. However, in looking at the Wireworld offerings, I don't know how the Aurora and Stratus lines stack up to the Venom 3.

Can anyone tell me which Wireworld line is more comparable to the Venom 3. Price wise, the Venom kind of sits in the middle, although it appears to be much closer in price to the Aurora 7 line.

Thanks in advance.
