korean dx mecha vs japanese dx mecha?
 

so ive been told that the korean and japanese gaoranger dx mecha are different, with the korean dx mecha being badly made... how do i tell the difference between them so that i buy the right version?

btw what are the differences between the japanese and korean versions of the dx mecha from the following series? and are they like the korean dx mecha for gaoranger or are they exactly the same except for packaging and ill have no problem buying either?

1: hurricanger
2: abaranger
3: shinkenger
4: go-onger
5: goseiger
6: gokaiger

I'm pretty sure the only differences in that list are that the Hurricaneger mechs lack die-cast and the Go-Onger have quieter sound clips.

Pretty sure Abaranger, Shinkenger, Goseiger and Gokaiger remained the same.

I've heard people say that the Gokaiger ones had sloppier paint apps.
