I think you're asking about Dapper (ORM) which could be compared to Entity Framework. The two major things to think about if comparing would be simplicity and speed. Dapper is simple to setup and use. It uses standard SQL and it's very fast. On the other hand, this is not a fair comparison. EF is has many more features and options. Use the right tool for the right job depending on requirements. Elmah and NLog are not apples to apples either. Elmah make dealing with "Unhandled" exceptions very simple. Nlog is for application logging (Trace, Info) and exception management (A try catch scenario).
