I generally prefer metal to resin figures. This is because I have my figures painted professionally, so I end up with quite a lot of money spent on each figure, and the last thing I want is for a figure to break.
Even before the invasion of Ukraine, Avanpost was producing more resin than metal figures. This may have been my imagination, but I decided that the proportions of their resin figures were slightly different to the proportions of their metal ones - I decided that the metal ones were thinner - and I preferred the proportions of the resin ones.
