Best setup for optimal opsec when carding. Linux, whonix or qubes? VM or no VM?

[Fan1k]

What would be in you opinion the safest way to do carding operations?
Host machine with Linux OS installed then USB stick with Linux installed and we boot from the USB install VPN + RPD and card?
Or should we use Whonix or Qubes in the host machine and in the VM Win 7 with VPN + RDP?
Do websites recognize when we are using a VM?
