That depends on what you are using them for. Oxygen barrier caps absorb the oxygen out of the bottle headspace. This can help preserve hop aroma in lightly flavored beers, and is recommended for beers bottled for competitions. Keep in mind, however, that most commercial brewers do not use oxygen barrier caps, and great beers can be capped with regular bottle caps!
