Ergo Proxy! I watched that after having seen Texhnolyze and craving more of the same vein. If you haven't seen Texhnolyze and enjoyed Ergo Proxy then it's imperative you see it. The soundtrack is also mesmerizing. If I recall it's the same creator, so there are definitive similarities, particularly in it's bleakness and tone. I definitely feel that Texhnolyze is the stronger of the two.
There's the soundtrack from Texhnolyze. I haven't actually listened to it, but I recall moments when watching that I was totally dazed by the music. I'm a big fan of GITS and Death Note, but I haven't seen the others on your list. In contrast to the perspective in the comment you link, I think anime sometimes has the advantage that it's frequently built off manga. This can (not always, but quite commonly) mean that each series is built off an arc that has a definitive plot. As in it ends. As in each episode moves forward with consequence and purpose. Each one is tuned as a means to an end. Most production TV shows do not have this advantage. They are forever seeking renewal season after season. They mean to go on forever. Naruto is one such case like this and is inevitably garbage for this reason if not many others. But in anime you find so many shows that have one or two seasons, because that's all they were ever meant to have. Don't get me wrong, a lot of anime is garbage. It's the symptom of being a genre historically mostly aimed at young-adults and children. But qualities like the aforementioned one have really helped it to transcend those bounds to tell great stories.
