I used to get tipped in eggs by this wonderful human at a bar I worked at and while I'm not sure I could tell them apart in a blind taste test I can say that the variety of pretty colors the egg shells came in and the richness of the yolk combined to make them noticeably more satisfying. I have a lot of experience tasting things though, I could absolutely see someone having a similar experience to mine and chalking it up to a superior taste. Or maybe there is a regional component to basic grocery store eggs and I live in a high quality zone, idk.
