Pro Supports post-update hooks
vim-plug allows you to automatically run arbitrary shell commands after installing or updating a plugin, which is useful if the plugin needs to be compiled or
make installed after an update.
Con Doesn't directly manage plugins
Other plugin managers will install, enable, and disable plugins for you. This one doesn't. If it's in the bundle directory, it gets loaded, if it's not, it doesn't. This can make it difficult to debug which plugin is causing some unexpected behaviour, as there is no simple way to enable/disable loading a plugin.
