What are the differences between toggle bolts and drywall anchors, and which one is more suitable for hanging heavy objects on drywall?

Toggle bolts and drywall anchors are both used to hang objects on drywall, but they have different mechanisms. Toggle bolts have a spring-loaded wing that expands behind the wall to provide strong support, making them suitable for heavy objects. Drywall anchors, on the other hand, are plastic or metal inserts that spread out behind the wall to distribute weight, but they are not as strong as toggle bolts for heavy objects. Toggle bolts are more suitable for hanging heavy objects on drywall compared to drywall anchors.
