I don't think it is cleaner, because usually we architect our applications in logical blocks.
For example when sending a data packet over the network and it fails, I don't care if the error was in the communication, buffer, socket level or network layer, just that the packet could not be sent.
That is what we need to retry, sending a new packet, not the lower level operations.
Languages with exceptions, which I use since 1993, allow me to choose using an exception, transform it into a plain error code or monadic error. I can have it all and choose which flavour I want to use, depending on the use case.

But as you say, it is a matter of style.
