Ask HN: Quantity or quality when it comes to open source contribution?

I think it has been mentioned many times by now, specially with the "reverse job application" threads, that a recruiter would give considerable points to someone contributing to open source in his/her free time. What in your opinion looks better on a resume, a good long list of open source projects one might have had sent a few number of patches to, or a one or two projects with more significant contribution?
