WPS is the quickest way - if the router is old and still vulnerable to the many exploits.
Capturing the four way handshake and cracking the key is a longer way to do it and generally for "home" wifi setups this will work in nearly all cases, you do need a compatible wireless card to be able to place it in monitor mode for this to work though. If you have compatible hardware the hardest (Read: most time consuming) part will be cracking the key if they have a half decent one.
