If we talking OPSEC, PIA of out, as any other with your payment info. You'll need to have few different anonymous VPNs and self hosted VPNs/proxies to make random chains. Pay by coins only, throwaway emails.
No VPN service has my "payment info". Or at least, not any meaningful payment info. As you say, I use email accounts created through Tor, and pay with Bitcoin that's been mixed at least three times through Tor, using a different Whonix instance and a different mixer for each mix.
