Ghosts I-IV: I-II or III-IV?

[Halo Infinity]

I'm actually a bit surprised that I didn't think of this sooner as I have always noticed how the Left of The Fragile is preferred more than the Right. This idea came from that topic.

It's also not just always about which side you think is better either. Perhaps it can also just be about the side that you prefer more and listen more to even if you like both sides. I also understand that Ghosts I-IV is split into 4 parts, but I'm also just going by the CDs as they are.

As for me, I still find myself leaning more to Ghosts III-IV.
