i personally don't care what version to get as long as i get the material i want. yes, there are noticable differences, but it's usually minimal or doesn't affect the actual product itself. overseas presses, usually from Hong Kong or Taiwan, are exactly like the Japan presses, imo. they just have an extra translation sheet and/or the OBI/sleeve is printed in Chinese.
if i couldn't get the "First Press" or "Limited Edition" of a Japanese press, i definitely rely on overseas versions to get it if it's available (i'm not going to settle for a measly Standard/Normal Edition if there's a Limited Press is out there!). it's cheaper too, which can benefit those who can't get the Japan presses, because really,
they're expensive. you can get more with your money. just make sure they're officially released by avex asia, Sony, etc.
tbh, the only drawback to buying the OS press is the fact it's not counted on ORICON. but i like to remain optimistic and say you're helping them expand in Asia with your OS purchase. LOL.
