I like them, but find I use them mainly when doing large piecing & even use them for regular sewing instead of normal straight pins. They don't get lost like the small ones do. I find the flat flower head pins are nice & really like the small glass heads for small piecing & curves. For smaller quilt projects, like tabletoppers & bench covers, the yellow head pins work to hold the layers together better than safety pins & because the heads are large, they are quick & easy to remove while machine stitching. So I'd say having an assortment means you'll have the right one at the right time.
