Oxidation is a much bigger problem short term for beers like IPA than most other style. Hop oils oxidize very quickly. But if you drink them in a month or maybe even two it probably won't be an issue. But if you are going to be keeping them long term you certainly want to minimize oxidation as much as possible. I recently went so far as to change the way I dry hop (using a purged vessel to hold hops and push into fermentor) and it has added remarkable shelf life stability to my IPA.
