The Zpacks Altaplex and Zpacks Duplex Lite take different routes to the same job. They are close enough that this really is about which handful of specs you weight most.
The Altaplex is 2 oz lighter, better space-to-weight, and taller (58 vs 48 in peak). The Duplex Lite is more doors (4 vs 2) and more vestibules (2 vs 1). Their GearScores land within a couple of points (85 vs 83), so neither runs away with it.
Pick the Altaplex if you care most about low weight and space-to-weight, which makes it the better call for counting grams on long miles. Pick the Duplex Lite if doors and vestibule storage matter more to you, or you are focused on comfort and room to move.
