I've been jumping between Sapphire and Kangerade for a couple of weeks now. After the release of 0.8.4 I think I'll be sticking with Sapphire for my daily driver. I have had zero issues since flashing 0.8.4. My battery life has increased from previous ROMs, temp is a little lower, quadrant and linpack scores are great. For me, it all comes down to the fact that it will work (and work well) when you want it to.
I have been doing the same myself, really happy with this Rom. Just need to change the boot animation and all will be well.
