npm shrinkwrap vs install passing the --save-exact flag

What's the different between using npm shrinkwrap or always installing dependencies passing the -E or --save-exact|-E flag?

ie.: $ npm i redux -SE -SE being the shorthand to --save --save-exact

I guess shrinkwrap will also take care of locking 'dependencies of our first level dependencies' but would it be a bad practice to always use --save-exact instead? If not, when or why would we ever need use the --save-exact flag?

Edit: I'm also starting to see people suggesting to config npm to install exact versions of dependencies by default:

ie.: $ npm config set save-exact=true

Now, if we do that, do we still need to shrinkwrap our project?

save-exact work like just save this version for you but it wont lock dependecies of dependencies

shrinkwrap makes deep locking.
