By using tor regularly without using a VPN you mark yourself for attention for the authorities. That's 100% fine if you've got nothing to hide and just use it for anonymity because you are a journalist or something.

Meanwhile for secure anonymous browsing you shouldn't log in with tor whilst using it and should be using a VPN also.

For general browsing where you don't want your government pilfered metadata containing things like harm reduction websites you should use just a VPN.

Hopefully this provides some clarity.
