Arnold’s neck and jawline, particularly in T2, are so unique that it’s impossible to do true justice without the head and neck being one piece. If Enterbay made the neck more accurate with a posable head, you’d have some very obvious gaps where head and neck don’t meet. I think the BD figure does a good balance of having the unique shape under his jaw that is trademark, while filling out the neck enough to hide the joint as much as possible, and the face is such a thing of glory I don’t even notice the neck when he’s on display.
NECA’s sculpt is great for a 10 year old sculpt for a $20 figure, but as we often say, still using it 10 years later without even slight touch up is either arrogance thinking it’s perfect or insult not caring.
I still think that EB BD T-800, even if not perfect, has come closest to feeling like Arnold lept off the screen and onto a shelf.
Under the right circumstances, I think the NECA 1/4 will look just fine on display, the only flaw I see to cause hesitation in getting it based on quality is the face and lighting, pose and viewing angle can compensate that.
