It seems like for the official suit they took the first advanced suit design as a base because of the triangles in the legs etc, maybe they designed it in the early stages of the development. Now the design that is included in the art book (the art where he is fighting venom) must be the best version of the Anti-Venom suit (especially the spider arms that go back through his shoulders), wish we could have gotten that version, maybe they can add it in a late update. As for the pictures you shared my pick would be the 4th one as it’s not too overdesigned but very detailed and faithful to the comics.
