Mushrooms are hands-down more profitable, however, they are getting a re-balance in the next update to produce every other day instead of every day, so fruit bats might not be so bad.

I’ve gone with mushrooms in every save except my most recent one, and I’ve found the fruit cave mostly disappointing.

The benefits are if you get lucky, it helps you complete community center bundles faster, and if you go with a certain foraging profession, you’ll get iridium quality fruit from the cave faster than the several years it takes for fruit trees.

That said, I’ve found it’s more likely to produce fruits that can be foraged rather than fruit tree fruits, if it produces fruit at all.
