My tier list:
1. in a basket (even the smell is amazing).
3. scrambled then seasoned.
5. side dish: hard-boiled (salted) or deviled.
6. sandwich (hard boiled from egg slicer as an ingredient), love these for picnicking. bonus if the bread was previously frozen and on the dry and crumbly side. also a stretch for "sandwich," but cut into strips and rolled into gimbap.
7. fried (both sides, over easy's fine), or sunny-side on bibimbap (c.s.b.: I was taught "how to eat that" by a frustrated, random asian grandmother at a restaurant. reminded me of my own. spoiler alert: you're supposed to mix the contents! good times).
I should mention the low-key trailer park freezer bag omelette. Simmered/boiled with whatever else you want in the bag. For me, diced hot peppers (habanero sweet spot). Very easy to make for lots of people at once who want different contents. You can just put their name on the outside of the bag.
Note for hard-boiled, the mineral oil preservative on the shell leeches out when boiling, effectively making them go bad faster. Sweet spot I think is don't let them sit longer than about a week.
