For magicka regen. This became a thing after sustain was hammered hard with the Morrowind update.
Edit: but your correct that the blue food gives more max stats. If you don’t need the regen then use the blue though top builds do not have regen on jewelry or set bonus except healers.
The more stats a food effects, the lower the effect on each stat. You might want to use a blue over a purple because the two blue buffs will give you larger buffs to the traits it's buffing and depending on your build you might not care about buffing everything. A good example is that if you are near max rank you might not care about getting a health buff in a NM dungeon, so you might want peeled eyeballs over witchmothers because you will get slightly larger buffs to magicka and magicka regen from the eyeballs than from the witchmothers at the price of no HP bump.
To answer your original question, longfin gives you max health, max stam, and max magicka where witchmothers gives you max health, max magicka, and magicka regen. On a magicka build that magicka regen is going to be more important than having an increase to max stamina (at least for most people). That's why people say witchmoters over longfin.
Witchmothers max magicka and health should be the same amount as the longfin, though. Witchmothers scales based on your level where longfin is a set level. They would only appear different if you were looking at the witchmothers while at a lower level than 160.

Thats the thing, longfin actually gives you more health and more magicka than witchmother, only it doesnt give you regen
