Paramount US 4K Blu-ray > Capelight DE 4K Blu-ray (caps)

Although the provenance of Paramount's 5.1 track is not confirmed, the fidelity is outstanding and speaks for itself.
The 7.1 track on the Capelight/old Lionsgate release is just an upmix with nothing gained over the 5.1.
The original stereo mix is only present on older DVDs and LaserDiscs; all Blu-ray 2.0 tracks are downmixes.

Paramount 4K Blu-ray has no extras, Capelight 4K Blu-ray has most of the extras, Olive Films Blu-ray has a exclusive commentary
