I don't know a whole lot about coffee, but I stand by that good tea can be brewed well using boiling hot water. I run a direct to consumer tea business and much of my family is involved in the farming and production of tea, specifically Wuyi oolongs. Very rarely do I intentionally reduce the temperature more than a few degrees - and that is usually by boiling the water and then waiting a minute before starting.
It's different for Wuyi oolongs, they're much closer to black tea so they can withstand boiling water. If I did the same for a green dragonwell or white silver needle, it tastes terrible. I also ran a direct to consumer tea business so I've also tasted quite a lot of teas as I'm sure you have as well.
