Is a security seal or EV SLL more important?

Does anybody know of a survey or study that compares site visitor attitudes/perceptions to security between an EV SSL cert and a security seal?

The EV SSL cert will show up green in the URL (like a bank) and the security seal is usually in the footer and says something like “secured by” or “hacker proof” or “website protection”

I’m looking for evidence that if you could only chose one, which would it be?
