The short answer

Edition v2026.Q3 · pricing and status verified 2026-08-06.

Choose Meta Advantage+ for any B2C or product-led startup buying its first tested demand — give the machine budget, objective, and fresh creative; it does targeting, placement, and bidding. Choose Google AI Max + Performance Max for capturing existing intent — when people already search for your category, and for retail feeds via PMax and the new AI Max for Shopping.

On the elems table, Meta Advantage+ holds seat #1 of the Paid Ads element and Google AI Max + Performance Max holds #2 — this is the closest call in the category, and the honest answer depends on which trade-off you can live with.

The case for each

   Best for Any B2C or product-led startup buying its first tested demand — give the machine budget, objective, and fresh creative; it does targeting, placement, and bidding.

   Watch Opacity is the product: Advantage+ hides the levers, and price-per-ad rising 12% YoY is auction inflation you eat. Account bans with no human recourse remain a real startup risk. Creative is the only input you still control — quality and volume of it decide your CAC.

   Best for Capturing existing intent — when people already search for your category, and for retail feeds via PMax and the new AI Max for Shopping.

   Watch PMax happily claims brand-search conversions you would have gotten free — always split out brand. Lift claims are Google's own, and channel-level reporting is still partial. The AI Mode transition is a live risk: as answers replace links, your search volume is being re-auctioned under new formats.
