I think you have to look at the two packs as specialized tools for a given job. When you run the numbers on a direct comparison things look OK, but when you factor in respective use, each is the clear winner in its own category.
The Catalyst would struggle in scenarios that the Arctic Pack shines, and the Arctic Pack leaves me a little wanting functionally for trail hiking.
Could you use a circular saw for tree trimming? Sure…but a chain saw works much better. Better to use the right tool for the right job.
