Log all request of Web API 2 (DelegatingHandler vs ActionFilterAttribute)

Searching on the web I found differents solutions to log all requests received by a IIS server.
 

• Solution 1: DelegatingHandler
• Solution 2: ActionFilterAttribute
• Solution 3: The IIS log

I read all articles about these differents solutions and I already implemented and tested them. I don't know wich one to choose between solution 1 and solution 2. Is there an history or performance or architecture maintenance reason that explain a solution is better than another. Are DelegatingHandler and/or ActionFilterAttribute a old feature?
