IRON vs Digit V4

IRON from XPeng and Digit V4 from Agility Robotics target overlapping use cases, so the decision usually comes down to price, payload and how soon you can actually take delivery. At least one of the two has no public list price, so budget planning means talking to the maker directly. Digit V4 carries more payload, which matters for material handling work. Availability also differs, so check the shipping window before committing.
