Honestly it depends on what you want out of it. I put it on and I got crazy download speaks compared to KK. The downside is the IR blaster, knock code, and quick circle no longer work, and in my experience unless there's a kernel leak or some dev really tries to get it to work, you just have to learn to live without some of those OEM hardware features.
Other than those three things (and the rest of the phone's bloat, although the stock launcher was pretty) I've had no major issues with 5.0.2 (tried both Illusion and AOSPAL.)
My advice is install TWRP if you haven't already and back up the phone. Copy that backup somewhere safe so you always have it just in case you format the wrong thing or delete it on accident. Then flash and try whatever you want, if you hate it download something else and flash that. If you hate that too just restore that backup and all is well. Although I'd do it late at night when you're not expecting any calls.
