It seems like you are doing way more error checking on the Web API version than the Nancy version, which un-fairly complicates the Web API code. If there is any automatic error handling that Nancy does, Web API could do the same to automatically turn un-handled exceptions into the proper responses.

Agree with @jrharmon. Even though this is 3 years old it is appearing in google searches. It is not a like for like comparison... should be updated to be more realistic.
