You make a good point.
Thankfully the technologies/approaches are clearly advancing, and the existence of strong competition only enhances this and is good for us collectors.
That said I have to believe that this InArt Joker will hold up for a good amount of time. I think it will be like what
@Wor-Gar said about the Nicholson Joker.
I think the people who are already throwing dirt on this figure bk of the Hot Toys Artisan Joker are premature …the Artisan figure does look good but at this point is only a prototype. I have only been collecting Hot Toys since 2017 but it is clear to me that they are very capable of turning out some amazing final products but they also sometimes produce figures that are significantly less impressive than their prototypes.
