CyanogenMod has more nonfree firmware and nonfree userspace libraries.
Replicant replaces some of these libraries and modifies the free code to
not require 3d acceleration which requires nonfree libraries on all
supported devices.  CyanogenMod doesn't use these replacements unless
they have all features of the nonfree ones.

Any source for this?  Many devices supported by Replicant have a single
Broadcom chip providing wifi and Bluetooth which is separate from the
modem (see e.g. [0]).  Tablets without the modem have that chip too.
Wifi and Bluetooth have free kernel drivers and nonfree firmware, unlike
modem which has also a nonfree userspace driver in RIL that Replicant
replaces.
