There's a specific kind of chaos that happens by the front door right before you leave the house, patting your pockets, checking the counter, checking the counter again, while your keys sit exactly nowhere. A hook by the door fixes that in a way that feels almost too simple to work, but it does, and once you have one you wonder why you spent years without it.
For finishes, I'd steer toward something in matte black, brushed brass, or plain white over anything shiny and chrome colored, because shiny chrome shows every fingerprint and water spot within about a week. Matte finishes hide wear, and brass especially gets better looking as it ages rather than worse. If your hooks are going somewhere damp, like a bathroom or mudroom, stick to finishes rated for moisture, because cheap plated metal will bubble and flake faster than you'd expect.
Where hooks fall short is weight. A single small hook is fine for keys or a light scarf, but the moment you hang a heavy winter coat, a bag full of library books, or anything with real bulk, a flimsy hook will bend or the wall anchor will give up entirely. If you need to hold real weight, you want a hook rated for it and ideally screwed into a stud, not just stuck on with adhesive and good intentions.
Adhesive hooks and plaster walls are a bad combination, and so are adhesive hooks and anything textured, like the slightly bumpy plaster you get in a lot of older buildings. The adhesive needs a smooth, clean surface to actually hold, and on a textured wall it will peel away eventually, usually when you're not around to catch what falls. Tile is better for adhesive hooks than plaster, but even then, check the weight limit printed on the packaging rather than guessing.
When you're buying in person or unboxing one at home, check the back of the hook where it meets the wall plate, because that's where cheap ones cut corners, with a plate that's too small for the screws or too thin to sit flush. Give the hook a gentle tug before you commit to hanging anything heavy on it, and check that any screws included are actually long enough for your wall type, since a lot of multi packs include short, generic screws that work for drywall but do nothing useful in plaster or brick. A hook that feels solid in your hand before it's even on the wall is usually the one that's still holding your coat a year later.
