The plastics are inferior IMHO, in the end the company died.
Go for the metals from Rackham they are beautiful, just beware of flimsy, tiny joints when you get the ones that need assembly.
The creators were always more concerned with the looks and less with miniature building mechanics.
I had Zombie Cavalry that looked awesome when painted, but assembling those tiny arms to the bodies and then adding a shield was ...interesting.
Still worth it though.
Look for the Drune ( Evil Barbarians) especially the ones on the massive warhorses.
