Dark Alex is amazing, and his firmwares were pretty easy to install, especially if you have a guide you are following. However, now that DA is gone from the scene, M33 is picking up the torch, and they are every bit as good as he is (although they built most of their stuff off his) Basically, M33 is the way to go if you want to stay in a current custom firmware, and those of you still on Dark Alex OE firmwares will have to upgrade eventually.
Basically, the CF scene is in good hands with M33
