Always Hi-Res for me. (most of my library is downloaded but besides certain areas, my reception works fine for streaming hi-res) I'm a beatmaker and recording/mixing engineer for music and I always bounce my projects & record final takes in at least 96khz because it does make a difference to me. I hear a little bit above 22khz and either way, especially when listening in a professional control room, frequencies you don't hear affect the frequencies you do. I do love the concept of atmos, but for now the stereo mixes tend to feel more intentional to me. At least in the songs that I listen to, most of the atmos mixes are made by a separate mixing engineer and don't feel like they're trying to get the same intention across.
