Well, I'm back to Quiver now, mainly because each Quiver Note can have multiple cells. I can first have a rich-text cell to document and provide links for the snippet, and then a code cell for the actual snippet.
The search in SnippetsLab is still superior, but the Quiver dev says he's working in improving Quiver Search, including adding Spotlight Search.
Bottom Line: Try both, and see which one works best for you.
