Got a few minutes to pull out the USS Arizona mini last night, assemble it, and pull out the W@S mini to compare it to:
The model consists of a resin hull/base, with multiple metal add-ons.
Some of the parts (masts and cranes especially) were a bit fiddly and a challenge to get off the "sprue" without damage.
Sadly, the posts for the turrets are too long to permit magnetizing without modification (this pic shows two 1/32" thick magnets in the well, with the "B" turret on top.
Here is the mini next to the WotC mini. As one might expect, the overall proportions and level of detail are nicer, though the barrels of the turrets on the Warlord version do look a bit chunky.
The tripods in particular are much nicer than the WotC mini, and the new model also has more details such as the boat and aircraft cranes.
Overall, I think the level of detail on the new Victory At Sea mini is much nicer than the WotC mini, though were not quite up to GHQ level here. Not sure how it compares to a 3-D printed one, though.
