Caps #1 (with FEL), caps #2

The compression is underwhelming on all discs, but despite trading blows in various frames, Lionsgate's re-released 4K disc wins.

The Lionsgate 4K re-release includes original matrixed Dolby Stereo mix, transferred from a LaserDisc, with missing cues at side changeover points corrected, and consistent volume throughout, as well as two remixed variants in 5.1 and 7.1 Atmos. The 5.1 is incorrectly labeled as original on the menu.

Resen 2020 Spain Blu-ray, old WEB-DL (pre 2023/2024 transfer), HDTV rip, or 35mm scan better than 4K Blu-ray with terrible "AI" upscale: screenshots

Shout! Factory 4K Blu-ray - caps.

's audio is also better than most previous releases as their 5.1 isn't clipped

All foreign language tracks were pitched too low, replacement disc and Ultimate Knockout Collection disc fixed the error. 

The Steelbook and UK standard edition are the same disc as the 2023 knockout collection. 

• 2015 Lionsgate Blu-ray (but it's missing the extra scenes in the Ultimate Edition)

• 2017 StudioCanal 4K Blu-ray and subsequent 4K Blu-rays are notorius for being heavily denoised and smoothened. Alternatively, 35mm scans for the theatrical cut is also available.

• For the Ultimate Edition with the T-1000 searching John's room and the happy future ending, the 2009 Skynet Blu-ray, which is the older pre-2017 transfer, but has DNR.

Differences of mixes on various releases: see thread and more info here.

2017 Blu-ray (which has the DNRed transfer), the 2009 Skynet Edition Blu-ray, and the 2000 Ultimate Edition DVD have exclusive extras. The 2003 Extreme Edition DVD has some exclusive easter eggs.

• 4K caveat: A variety of VFX set pieces and touch-ups were added in scenes throughout the film, probably for continuity or consistency, although they might be unnecessary or revisionist. Clouds are added to clear sky of the last act.

• AI is used to fix an unwanted camera movement in one scene.

• some shots had been further stabilized, resulting in strange motion blur.

Also has missing dialog intact.
But it can be argued that the Warner Bros 4K Blu-ray 5.1 (remix) is technically a better mix.
