I think the reason why I love Riarkle more than Rucas is because Farkle is still in love with Riley. You can obviously see that he loves her by the way he looks at her, but he stepped back because of Lucas. It's even obvious that he loves Riley more than he even loved Maya. He claims that he loves them both equally, but he shares more moments with Riley and he gazes at her constantly throughout the show. Sorry for the rant, I just really love this ship x3
