Are filament vacuum bags worthwhile?

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?
