Are filament vacuum bags worthwhile? (sh.itjust.works)

I finally got a filament drying box and I'm using it prior to and during prints. It seems to be helping. I'm a bit of a color queen, so I keep a pretty big backlog of different filaments. I've been storing them in vacuum bags but the vacuum bags often seem to lose some of their vacuum after a few months; the whole process is a bit of a pain. Is this really worthwhile or as long as I'm using the drying box can I forgoe the vacuum storage? If vacuum storage is still a good idea, are there better bags I should be looking for that don't lose some of the vacuum after a few months or is that pretty standard?

Instead of those bags with a valve take a look a the kitchen department. They have vacuum seal machines used for sous vid cooking.

This is practically identical to the original packaging and can hold the vacuum for years to come. Leave the bag longer than required to allow it to be resealed multiple times (roughly 3cm are cut with each opening & resealing).

For the frequently used filaments place them in a drying box.
