I mean, it pretty much comes down to how much you trust your VPN. Depending on your jurisdiction, trusting someone that is legally forced to keep logs vs some who's income and reputation depends on not doing so might the best bet (through VPNs definitely have survived giving out shady data).

Also, if your VPN is located somewhere exotic and just somewhat uncooperative, the bureaucratic overhead of getting the logs, getting the IP, sending the request to your VPN and then matching the result with your ISP might be long enough for the logs to expire.
