"Best" depends on what you search for and how often. For power users that usually means:
instant results as you type, real filters, optional content search, and no subscription.
Here's a clear checklist — then how popular options compare.
What to look for
Search-as-you-type speed — results should feel instant, not "wait for indexing"
Folder control — choose what gets indexed, especially external drives and project folders
Deep filters — type, size, date, and query syntax beyond plain filename matching
Content search — find text inside documents when filename isn't enough
On-device privacy — your file index shouldn't require an account or cloud upload

Our take
If you mostly launch apps, Spotlight with ⌘Space is fine.
If you hunt for files daily — especially on external drives or with specific filters —
a dedicated app saves real time.
