Question: Advantage blitz4j vs log4j2 async logger

[leozilla]

I haven't found a good comparison of blitz4j vs the new log4j2 async logger.

Can somebody give me a short answer if it is worth to change to blitz4j if I already have log4j2 in place.

I know blitz4j provides more features like handling log storms which comes very handy but from a scalability (less contention etc) pov I dont see a real reason (in fact I think log4j2 performs better because of the Disruptor).
Is this a reasonable statement?
