There's the Ace of Arrowblades emblem, which requires an S rank on all missions. I definitely don't see it very often, and getting an S rank on the last three missions can be a challenge.

Outside of that, the hardest emblem to get that's available to all players would be the Golden Wings, which requires completing the "level any five aircraft to Lv.5". There's also the "Four Leaves" emblem, which has to be dropped. It's considered to be the emblem with the lowest drop chance.

Besides those, the only emblems difficult to get would be from Ranking Tournaments, which are obviously rare.
