I personally like m2e style, great 3d sculpt pictures, with inspiring concept art. If I would display bare plastic I would suggest a few options a mangnified view, 3d scuplt preview video on display and or prime white wash black pops details perfectly without a need to paint. Grey from a distance makes it hard to see detail.
I prefer no studio paint in malifaux line only because outside of guild and Korps there isn't much of a uniform to color schemes.
