Nope. 6T's low light performance is on par with the Pixel 3's, and Apple's gen equivalent of the Xs doesn't seem to perform as well, and the S9 also had slightly worse night performance.
The only way people can beat the 6T and Pixel 3's camera is with the newer phones: the 7 Pro, S10, Honor 20, Mi 9, the Pixel 4 (when it finally comes out) all use the same sensor: the Sony IMX586.
You may be just simply stating you don't like the 6T's camera app... it does low light differently. Not worse, but different, and in my opinion, more accurately. People have put a copy of Google Camera on their 6Ts and enabled the Pixel 3 low light mode (it's entirely in software and not a function of the hardware; change a prop, and any phone gets the Pixel 3 enhancements), and the 6T either performed essentially identically, or slightly better.
