I have a german made Star bass II in sunburst, I have not played the Asian made ones but the German one is as good as you would expect, the neck on these things are phenomenal and they sound great.
One huge difference between the ones made in Korea (Pro-Series) and the more recent made in China Rockbass-models is the scale lenght of the 4-string models. The korean ones have a "34 scale while the chinese ones have a "32 scale. I have a korean one. The build quality is exceptional good, but on basses with this design, a 34" neck is actually "longer", 'cause the bridge on the bodies is not as close to the edge of the body as on a classic Fender construction. So you have to push the body into the opposite direction of your fretting hand or your fretting hand has to reach further away from your body to reach the first frets. I never thought about it before owning one, but this is the reason, so many similar hollow body basses are shortscale. View attachment 2962629
