Not only concerning about video, but I like to have original audio too. It seems all too often that an older film needs to have Atmos to get 5 stars in audio department, but I’d be more happy to have an original DTS or even stereo or mono mix in there, or at least a faithful adaption to 5.1 (unlike e.g. The Terminator). And even though it may get overboard sometimes here, I still respect their opinion and I know there is a lot of knowledge on this site that many online reviewer doesn’t share.

Die Hard BD was pretty poor but it also has gotten supposedly a great representation in 4K. Hopefully the sequels are arriving soon with similar care.

Edit: and also, the basic idea for this thread was to know what would be the go-to version to get the most authentic viewing experience if a new 4K version has been released. Is it the 4K, the previous BD, or any fan preservation of sorts. For example I only watch T1 and T2 from my preservation files since both BDs were botched.
