The ASUS ROG Zephyrus G16 GU605 wins for users needing GPU power, delivering 60+ FPS in modern titles where the Surface Laptop 6 15 cannot compete. The Surface excels in daily productivity with 15+ hour battery life per Notebookcheck tests versus the Zephyrus's 4-6 hours under load. This is a close call only if your workflow is strictly office work; otherwise the Zephyrus is the clear pick.
