Depends on the quilt size. Pinmoors in a small wallhanging works ok, but on a larger quilt, it just makes too much bulk for me. I prefer my safety pins on larger quilts. Plus, I personally don't like the pinmoors for other reasons (my cats love them, so that is a constant battle, to keep the cats away from them, they'll even pull them right off the quilt!), they are pricey, bulky and not much less time consuming than safety pins.
Personal preference for sure, but just some things to think about . . .
