Great question, and not one I can answer from a Support side of things. Personally, I’ve tried out a few of them and I enjoy the upgraded quality, however, I tend to listen to music more for background noise and don’t notice the quality once it gets to 320 kbps or so. Anything past that is good enough for background noise to me, which makes HD great occasionally, but generally unneeded.
If you do a lot of “lean in listening” where you’re really getting into the music, it’s probably a good idea to check it out. I know most services offer a trial period, you could always check it out for a month and see how you like it.
