Which is better SLF4J or Log4j2?

What is the difference between Log4j and Logback?

The main difference is that SLF4J is using static binding while commons. logging is using some resolution strategy. Logback (the "native" (i.e. there is no additional wrapper layer) implementation of the facade) is comparable to LOG4J but has a richer API.
