My issue with standard (non-toggle) anchors is that all of them will eventually fail even under normal household conditions.
As you use whatever is suspended from them, they wiggle and flex, which crumbles away the drywall they’re set it.
It’s not too bad for things like bookshelves, where things go on and off maybe 1/day, but something like a coat hook, where you might hang and remove the load multiple/day, will accelerate the disintegration of the drywall around the anchor.
Also, unless you’re real good or careful, anchors don’t sit exactly-completely flush with the surface. If the anchor is proud of the drywall, when you hang the load, it’s not tight against the wall and looks like crap. If the anchor gets recessed—at all—into the drywall, when you start tightening the screw, it’s actually trying to pull the anchor back out of the drywall.
