Emperor’s Children Terminators

I’m not a huge fan of the Chaos Terminators.

Their style is the reason that Emperor’s Children are my first Chaos army as I hate the conventional style of Chaos units and how it all seems to be around Khorne. EC are different and much nicer.

For that reason I’ve decided to use Horus Heresy Terminators instead of the Chaos Terminators as they look much nicer.

But the question is, do I use Legion Tartaros or Legion Cataphractii Terminators? Which look the best stylistically to make excellent Emperors Children Terminators? Or am I just completely wrong, and Chaos Terminators are the best? What are all your thoughts?
