These models look so cool!!
It is a pity that there are only such skins for the Reforged version and not the standard one.
Tbh WC3 started looking a bit outdated once WoW came out. But now, with Reforged it's a potato: A texture set for 1 unit can have 160 times (x4 with normal, emissive + ORM) the pixels of its Classic counterpart... so 1 Reforged unit could probably almost house most of Classic, lol.
Triangles in WC3 were always lacking, but the difference there is like 50 times the polygons now.
None of this applies to the actual work modders done, it was always an improvement from the stuff they worked with.
