The worst imo is the trendy "app shell" approach where the skeleton loads and then the content. Never quite sure if things are ready to interact with. Also ideally the shell should load the parts appropriately sized so when the bloated json payload is eventually rendered, the page doesn't jump around. That's quite rare in practice though.
