I like this one better because it can be interpreted in many ways. I saw it before the one with the dialog, and what I got from it was that Discord tried to steal the crown thingy and corrupt Spike, and as Spike was becoming more "grey" he looked and met Discord's eyes. Spike reminded Discord of himself (since discord was primarily described as being some sort of dragon), and so he went away without taking the crown. I like this version better because it shows that despite being some sort of cruel villain, Discord has a backstory and feelings.
I actually like this version better; Nopony really knows what discorded Spike would be like, and here it is left to the imagination. Yet you can still "see the dialogue" between them. it is really good.
TL;DR You unintentionally made me love Discord.
wow. xD Thank you.
