What is the point of counter type when we can do the same thing with int or bigint?

I just read the following link

https://docs.datastax.com/en/cql/3.3/cql/cql_using/useCounters.html


and I wonder what is the point of counter type when we can do the same
thing with int or bigint? what are benefits of using counter data type?
