I have close to 900 blu rays, with 268 of them UHD 4K disks, which is not part of the poll, but is generating my discussion. I usually keep somewhere between 20 and 30 movies I have not yet watched. I not only enjoy watching them, but I enjoy perusing my displayed disks, which is usually done when picking something to watch. Like many others, all of my physical media is displayed at the rear of my home theater room. I also routinely watch content from Amazon, Roku, Netflix, and maintain digital libraries with Vudu, Movies Anywhere, Amazon, Google, and FandangoNow. IMO Dolby Atmos, both from disks and streaming, has revitalized my interest in watching video and listening to the audio that goes with it. I love it when friends come over and walk my back wall looking at the available movies and deciding which one we are about to watch. My home theater equipment is far from top of the line, but I am proud of it, and enjoy showing it off to others. Hands down I prefer UHD 4K streaming to Blu Ray, but there are a lot of variables that must be met for that to happen. First, you have to have competent equipment that is calibrated so that it plays correctly. Second, (and probably first), you must have an adequate internet signal, if you are trying to stream. The last thing you want is buffering or drop outs in the middle of the movie. Your group won't hang around very long with a bad signal. If your ISP has a history of intermittent service, that in itself will turn you away from streaming. That alone is probably the biggest reason why I have hung onto my physical media as long as I have, and will continue to until something comes along better. Here's an example....recently the town I live in had a town wide weather related power outage that lasted 9 hours....no internet. On hour 3 we were watching a UHD 4K movie, as our generator was running the refrigerator, the LR TV and 4K DVD player. Streaming was not possible that day because my ISP was down as well. They actually were down for an additional 3 hours after our power came back on. One of my all time favorite movies never issued a 4K disk, Edge of Tomorrow. Did I purchase that movie from a digital provider? Yes I did, but it is the exception instead of the rule in my house. At Christmas last year, I bought the 4K Christopher Nolan collection, which did not include digital copies. Over the next 3 or 4 months, I purchased 4K digital copies to those same movies to keep my digital catalog as current as possible. Because my ISP is not the most reliable, and I own the house I am in, I don't have the option of moving to a location where better options are available. That alone is the deal breaker for me as it relates to streaming. In my opinion, 4K streaming prevails against blu rays, as long as a good signal is maintained throughout the streaming. Without a good signal, streaming doesn't work. (Sorry for being a bit off topic).
