They both tend to be used where you need impedance matching between the input and output circuits
common base: low input impedance, high(ish) output impedance with low capacitive coupling between input and output. Can be used in antenna matching input circuit for radio circuits.
common collector: high input impedance, low output impedance, non inverting, approximately unity gain. Output buffers / line drivers and similar.

A subset of Common collector circuits are known as emitter follower circuits. They are quite common, used as buffers and output driver circuits.
One place where common base circuits are used is in the upper (active load) portion of a Cascode amplifier. You can Google "cascode amplifier" for more info.
