Boiling potatoes with vs. without skin
I almost never peel potatoes. I like the flavor and texture of the skins, even in mashed potatoes, and unpeeled potatoes are less prone to becoming waterlogged.

According to Tablespoon.com, the Idaho Potato Commission recommends that you leave potatoes unpeeled for boiling for reasons of flavor and texture, even if you intend to peel the potatoes after boiling.
