Depends how you connect. VPN before Tor - VPN can see your real IP and in theory could log and correlate metadata. Tor before VPN - you’re anonymous to the VPN but you are trusting them but they can see your traffic. Honestly, if you’re good on Tor just use Tor. If you use a VPN, just use that. Unless, you’re doing some really shady shit, those I can’t help with.
