The biggest selling point I think my script has when compared to eatdrink or vcon is considering the spleen gained back from hobopolis consumables, which to my understanding neither of those do. I'm not 100% sure about that for vcon since I haven't experimented with it much, but I've used eatdrink for a long time and it has never used sliders or pickle juice for me, which this script finds as optimal for my valueOfAdventure.
It's not strictly optimal per se, especially because it tries to fill an organ all at once when possible, so if blood drive stickers are optimal it will usually eat one of them, a voodoo snuff, and a size 2 spleen item instead of eating a blood sticker, emptying spleen, and repeating.
It is still under very active development though, so it's getting better all the time!
As for how I decide what's "optimal," it probably is closer to pretty good than objectively perfect, the name is mostly just a cute acronym one of my friends came up with for CONSUME. To be kind of brief, it takes the valueOfAdventure * average adventure yield - price of item, then factors in the value of any organ cleanings in the same way, and sorts by this net value of a consumable divided by space taken. It then tries to fill up with whatever's best that fits.
