What sort of differences are you thinking of?
The "create table as" syntax allows you to
- clone an existing table
- create a table based on the results of a SELECT
- populate the table with data
- copy existing stats from the source table (I think only if you clone a table)
The "create table as" syntax does not allow you to add RI constraints.
