Personally, I would choose skills.
However, the final hiring decision often ends up being the candidate that has it all.
In the present job market, companies find it fairly easy to find candidates that have both the skills and the certs.
I remember years ago, my manager hired an engineer to do tech work because an engineer was obviously better than ANY technician.
An important point to keep in mind, is that having certifications and degrees shows a hiring manager that you are fully committed to your field.
I recall a vendor evaluation survey that I was involved in a few years ago. A large portion of the preliminary survey focused on the ratio of degreed professionals to all staff.
Like it or not, many factors influence the hiring process. Having appropriate degrees and certifications GREATLY improves your chances of being hired.
