The two syntax options are equivalent, it's developer preference which to use.
If you provide the reason string directly, then the two syntax options are equivalent, it is the developer's preference which one to use.
.. note::
The ``require`` function is evaluated just as any other function.
This means that all arguments are evaluated before the function itself is executed.
In particular, in ``require(condition, f())`` the function ``f`` is executed even if
``condition`` is true.
The provided string is :ref:`abi-encoded <ABI>` as if it were a call to a function ``Error(string)``.
In the above example, ``revert("Not enough Ether provided.");`` returns the following hexadecimal as error return data:
