Is it always better? No. It depends on your storage environment. If you have lots of humidity then storing in the fridge can help. In normal environments - seeds can be safely stored for years in a box on a shelf out of the direct sun and away from the heat just as most commercial seed suppliers do. With the exception of the alliums and some flowers, most will remain viable for years. Heat and humidity is what kills seeds.

As to the freezer, they can only be stored frozen if absolutely dry or they will rupture and mush when thawed. Most home seed savers don't get their seeds dry enough to safely freeze and it gains you nothing so usually isn't worth the risk.

If you are interested a search will pull up not only a FAQ on how to store seeds but many additional discussions on it that you can review.
