The Osprey Porter 46 and the Tom Bihn Aeronaut 30L are two formidable backpack options appealing to various travel enthusiasts. However, each carry a unique set of features that may draw some travelers more than others. The Osprey Porter 46, with a whopping 46 liters of capacity, gives a superior advantage to those who can't seem to travel light. The weight might also be a concern, but at just 1.5 pounds, this isn't much more cumbersome compared to its rival, the Tom Bihn Aeronaut 30L, which weighs 1.3 pounds. Osprey's Porter is, indeed, a big pack for those who carry more, and can still be cinched down to a compact size.

On the flip side, the Tom Bihn Aeronaut 30L, with its 30-liter capacity, presents a more compact and light option for the minimalist traveler. Although smaller in capacity, its compatibility with 98% of airlines enhances its convenience for avid globetrotters. This bag's material creates an edge, boasting of an ultralight 400d Halcyon/420d nylon ripstop 200 denier Halcyon/nylon ripstop fabric lining, which is stronger than the Porter's Nylon finish. This minimalistic yet sturdy construction labels the Aeronaut as top-notch quality and support on any journey.

To sum up the key considerations:

While the Osprey Porter 46 emerges as a perfect choice for packing lots and accessing items easily due to its clamshell opening, it also shines in offering better suspension and prevention from looking sloppy with its compression strap. Its lightness for the size and spaciousness further enhances its appeal. The Tom Bihn Aeronaut 30L, however, scores points for its high capacity considering its size, durability, and superior water resistance. Whether or not a laptop compartment is a requisite would also sway one's choice between the two. Each traveler possessing a unique set of demands should therefore weigh these key considerations and the corresponding trade-offs to hone in on their ideal carry-on backpack.
