It is also water proof, which may not seem important but it is for the unsuspecting collector who uses Windex to clean the slab. Most other holders just suck it right in like a sponge. Some worse and faster than others.
IMO the baggies should be your best friend. I've got plenty of examples of cards damaged by the rails and starting to see some damaged by the hard plastic gaskets.
In the end, it's all a matter of personal preference and what you feel is best for your cards.
