Apollo vs Walker S2
Apollo from Apptronik and Walker S2 from UBTech 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. Apollo carries more payload, which matters for material handling work. Availability also differs, so check the shipping window before committing.
