What Has Your Experience Been Like with CyanogenMod?

CyanogenMod ROMs are popular amongst enthusiasts for their sheer availability, their feature set and the (relatively) AOSP-feel it gives skinned OEM devices. Yet these are not always optimized or stable, sometimes earning the ROM a bad reputation among those with high custom ROM standards or devices that haven't seen stable ports. What has your personal experience been like?
