The Nimrod version is shorter, but it seems harder to tell whether error-checking is done right.

Nimrod has exceptions. I am catching them (https://github.com/idlewan/nawak/blob/specialpages/nawak_mon...) and returning a 500 error page with the detailed exception message.

So you need less explicit error-checking everywhere with a language that support exceptions.
