Adeptus Titanicus Choice of Legio Question?

Hello one and all,

I've recently picked up a box of Warhounds for Adeptus Titanicus, I love the models, and they look perfectly like miniature versions of the Forge World models.
Here is where I pause for thought, and the question for the post - have fellow titan players opted to do mini versions of their Forge World titans, or have they used this as a opportunity to try a new Legio? or side (Loyalist or Traitor).
Having read Titandeath and Doom of Molech I have found 2 other options that I like the look of other than Crucius, however, should I stick to my original Loyalist Legio? I do like the idea of having them to use both in AT and 40K, potentially sharing honours and kill markings across both formats.

What are your thoughts?

Thanks LH
