The fact that carriers deploy the latest security updates to Android devices much later than Google does to Google Play Edition and Nexus devices, should we avoid using those devices altogether?

Many good questions generate some degree of opinion based on expert experience, but answers to this question will tend to be almost entirely based on opinions, rather than facts, references, or specific expertise. If this question can be reworded to fit the rules in the help center, please edit the question.
Devices that are slower to get security patches are more vulnerable, all things being equal.
However, whether this means you should avoid them depends on your particular threat model and risk tolerance.
