A remux is a fully lossless video file, typically a MKV, that is just the video streams from a DVD/Bluray wrapped in an MKV container. It’s not a new encoding, it’s the original video, in its original codec, fully lossless.
I personally like knowing that I’m watching the best possible quality of any given media, without any extra processing. Most people probably wouldn’t immediately notice the difference between a high quality encode and a remux, but I’m a quality snob.
