Arrow 4K Blu-ray or Shout! Factory 4K Blu-ray

Arrow has a different grade and a better encode, though the difference in either is not major.

Original mix: Shout! Factory 4K Blu-ray (similar to Criterion LaserDisc, but less distorted)

Alternate mix: Scanbox Nordic PAL DVD

Surround remix: HK Video France 4K Blu-ray (5.0)

Arrow used the alternate mix, but with extra filtering and lowered dynamic range. The alternate mix has much better fidelity.

Arrow has a much better translation.

Arrow LE has the Taiwan Extended Cut which will not be present on the standard edition.
