Miniature Scale?

I’m really curious how SotC minis compare to other miniatures lines in scale, but I won’t be seeing the game until next wave. Does anyone know how the Doomtroopers compare to Fallout Wasteland Warfare minis, or are they closer to GW guardsmen, or Deadzone (Mantic) miniatures? Comparisons to other board games work too.

Any help would be appreciated.
