I'm sure this will come as no surprise but collecting 198 SP Gobbie Keys and turning them in did not even come close to outperforming taking 1M accolades each week instead of 6 keys lol. Admittedly they weren't all from unity so it's probably more like 20-25 weeks of keys (millions of gil) rather than 33.
Items with value - Cehuetzi Pelt, Voidhand: COR, Obsidian Crystal, Moldy Gorget, Heyoka Subligar, Turms Leggings, Herald's Gaiters
Interesting but not valuable - Argute Stole, Rabbit Stick, Nefer Kalasiris, Smilodon Mask +1 (surge walk drop), Herculean Vest
Also had a couple pieces of unity gear, even more delve gear and a ton of <99 equipment.
And an assortment of bits and bobs that might slowly sell for ~50k. Looking at it initially I thought that maybe if some of those NQ crafted items had been HQ then that would have swung the results substantially - however the HQs don't appear to have the gobbie box tag. So given that I'm not even sure how keys could be better than raw gil unless you got a jackpot AMAN item.
