Both animes are set in a apocalyptic setting. Male and female protagonist that work together against evil. 

This is purely my opinion, but I believe Clockwork Planet has a lot in common with Guilty Crown because it’s based around groups of people trying to save the world. They are also both Sci-Fi’s. 

W meets Y.. Precisely It involves... such Coils and Gears to collect them.. for Bio Technology.. Imperial weapons on a mission.. Automatons/Nendroid as their partners in crime.. Exactly similar where both are set in Dystopian Future where the world was about to get sucked on or get absorbed by it's titanium massive energy.. and become a wasteland 

- Both MC have a "slave" robot. - Both want to bang their bot. - Both bots want to bang their masters. - Both series are filled with clichés - Both takes place in the future. - Both have an "intense" head in lap scene. - Both bots are super strong. - Both series are equally "enjoyable". 

Both are created by the same person and have their own different interesting stories and characters 

So essentially, the main character has a harem of machines-girls and sends them to combat. It's like Pokémon, but with zettai ryōiki.
