The low light ability on the HTC One M8 is great. The M8 is following the path laid out by HTC with the M7 which was the first to take high quality low light pictures. I have not seen another phone on the market take a better low light picture then the HTC One series phones. though I am not a huge photo, the M8 allows me to take quality pictures even when the surrounding environment is not conducive for high quality pictures. This phone gathers all the available light via the sensor, allowing you to take that perfect picture even in a dark room.
Here's a low light picture comparison of a HTC One M8, HTC One M7, Samsung Galaxy S5, Samsung Galaxy S4.
(the pictures are in the same order m8,m7,s5,s4)
