The Ford PCV valve is preferable simply because it is less likely to hang up internally.
Have someone ride with you that is famillier with pinging.
A lean condition or EGR problem can cause pinging on acceleration. High octane gas will lessen pinging but of course the problem causing it should be corrected.
