Admiral:
Solid design. Useful miniatures, especially for our K’daai purposes.
Jackswift:
Not bad at all. A bit simplistic but easily converted with armor plates.
Carcearion:
I really like them! 
Like Jackswift said, simple but rife for conversion. Some chain beards, and hats and I’d be perfectly happy with them.
Firehammer:
The big one is okay, the small ones are uninspired and remind me of some Grenadier models from the early 90s.
I prefer the following bigger models by Mantic (sharing the same base body):
And I would be cautious with Mantic release dates, as I am waiting a year now for the release of Mantic’s future vehicles “Mule” and big drill thingy.
Ghrask Dragh:
Oh yes, great K’daai there Tjub, would fit right in with alot of armies on this site
