Product feed / catalog connection
This is the difference that decides everything else on this list.
OptiQube connects directly to your product feed. It knows what’s in your catalog, generates a creative for each SKU, and updates automatically as products change. Holo has no such connection — it doesn’t know your catalog exists. Every asset it generates is a standalone file with no link back to a specific product or inventory state.
Winner: OptiQube. Holo isn’t built to solve this at all.
