The iPhone Duo on Amazon (paid link) is a just release with a chip you’ll feel in every swipe, while the iPhone 11 Pro Max (paid link) is on the oldest still supported silicon and likely next to lose updates. The Duo’s battery will carry you through significantly longer, but it comes at a steep price compared to the renewed 11 Pro Max. If you need longevity and modern features, pay up for the Duo; if budget rules, the older model still runs the current OS for now.
