Why resin ??
Because you dont need to create a injection mold that it is very very very expensive but you dont see it since you will produce thousand of kits with one mold.
With resin you create you master duplicate with silicon RTV and you copy it with PU resin, it is easier for short production less than 100 pieces.
If you compare plastic kit vs resin kit for the same amount produce, resin kit will be cheaper.
You need to amortize the price of the mold that why plastic producer will release more than thousand copies.
Is it clear
