I do think there was more of difference even 10 years ago than now let alone that some of us recall the 20th century when 5 point articulation and minimal paint was the norm for 1:18 scale. That style was (and still is) cheap - when 1:12 scale took off it was a vastly different product in terms of detail, articulation, paint. I think the 1:15 scale was really the first step, with lines like Playmates Trek and Tozbiz pre-legends Marvel upping the game from 1:18 scale but still not at the level of 1:12 Legends and LotR and others.
1:18 has gotten much closer to the articulation, detail and paint apps that we see in 1:12 the last 10 years But I think when 1:12 first came on the scene they were not easier to make nor the same cost as 1:18.
