I just would add Log::Contextual to the list: infact when I wonder, as you, about some module I firstly check what is in Task::Kensho list.

Before other wiser monks add their experience I can say that if you already have a good experience with Log::Log4perl I see no motivation to quit it.

As everytime it depends on what ou need and what you expect by using a module. And it relates on the cost of importing a, possibly large, framework into your application.
