Medicom has a more screen accurate facial appearance, than either ss, especially with the shoulder armour, but v1's have fragile bodies, the shoulder joints may tend to "peel" apart broken due to some crappy choices in material....also they are more 12" figures than they are true 1/6 scale which should ideally put him near 14".
He is very small compared to ss.
The facemask and armour and chest box and belt and codpiece and shin guards are iPVC and abs dome.....weirdly shaped dome feels too big for mask, but overall ok.
Also gloves are hollow PVC not solid like ss
Ss parts are almost all abs and hard solid PVC ....
Sideshow esb has the more precisely sculpted features with multiple parts and details, however is more idealized....has a distinctive look as well....identifiable w oddly proportioned mask. Shoulder bells are I accurately detailed and the chest armour has a very basic look to it that has none of the nuance as the actual costume.
It is, however, a better size and has good quality about it that's worth the dough, including the light up features and stand.
Medicom 2.0 has none of the body quality issues that plagued the first version except the odd dome shape ( mostly a too roundly sculpted crown)
But is still it's a smaller scale and is better as a standalone figure....
For the money.... in order:
1. Ss sideshow esb
2. Medicom 2.0 or sideshow Anh
3. Medicom Roj or ros
