S25 HONG KONG/CHINA/KOREA/ETC

Which one is best ? I know some people know which versions are more limited for trying to use in states... and some arent so bad. (Keep in mind I am rooting the device) if I am located in U.S. . . . I shouldn't have any problem trading in a global model for a new global S26 ultra while still located in the states right? Samsung chat said : Go to HK samsung and choose : export. Any experience on this ?
