Should you version your REST API using the path, a header, or a query parameter?

hey folks, ive been wrestling with api versioning lately. for rest apis, whats your preferred method? sticking to /v1/resource, using a custom accept header like 'application/vnd.myapi.v1+json', or maybe a query param like ?version=1? each seems to have pros and cons for discoverability and client implementation. curious to hear your experiences and what makes you choose one over the others
