Reviewers call them both impressive. The Porter is praised for its capacity and durability, with one noting, "Bulk it up or cinch it down, the Porter is a reliable choice for those who tend to carry more." The ADV is not far behind as it is lauded for its lightweight construction, affordability, and the convenience of having an Okoban tracking tag.
