"Best " Topic

Edit: The title should have read "Which casting material do you consider best for 28mm figures?"
The current poll TMP link is on the topic of HISTORICAL miniatures, that leaves out (for example) the vinyl based miniatures such as Reaper Bones and does not differentiate between single piece plastics, multi-part plastics, nor does it to differentiate between more firm plastics like those used by the Perrys, softer ones such as those used by HäT, or resins such as those used by Black Scorpion, Hasslefree, and others.

I don't have enough experience to say with certainty which plastics and resins are different enough to qualify as different materials (i.e. is the plastic used by Victrix different enough from the plastic used by Warlord to list them separately? Is Hasslefree's resin different enough from Black Scorpion's to list them separately?). Likewise I doubt anyone has enough anyone can clearly state they are familiar with all the various resins used for figures, but collectively the combined experience of TMP users should be sufficient to note whatever differences may exist. In any case, I would definitely appreciate suggestions on the the differences between various manufacturers materials.
I also recognize that the difference between multi-part and single pose is not material in the sense that the same variety of plastic can be used to manufacture both. However, the difference in the experience of preparing & painting multi-piece & single-piece figures is significant enough that to list them separately.
So which material(s) do you prefer to have your figures made from?
a) multi-piece metal (e.g. every one from Essex to Old Glory to Foundry )
b) single-piece metal (e.g. some Redoubt)
c) single-piece soft plastic (e.g. the type usually used to manufacture 1/72 figures)
d) multi-piece soft plastic (i.e. the same as c. I have not seen any that fit this description, but they might be out there. Irrespective of availability, someone might want them)
e) multi-piece hard plastic (e.g. some Perry figures)
f) single-piece hard plastic (e.g. other Perry figures)
g) multi-piece resins (e.g. some Hasslefree)
h) single-piece resins (e.g. many Black Scorpion)
i) other resins or plastics(?) (please specify)

I don't care what they are made of, just don't make me stick them together, please…

B with A right behind. If I do plastics I prefer multi-piece (E) simply because it is easier to trim off any flash without worrying too much about breakage.
