Android Revolution is currently the most popular Rom for the original HTC One. Developer "Mike1986" has now released his Rom to the M8. It just so happens that this is the first ever rom for the HTC One M8. This is based on Kit Kat 4.4.2 and is built on Sense 6.0. This Rom gives you the stock look and feel of HTC Sense, there are plenty of customization options coming to this rom which will be featured in the Sense Toolbox which wasn't quite ready at the time of release of this rom.
