Differences between Mission Planner and APM Planner

Hi could someone tell me the differences between Mission Planner and APM Planner

APM Planner development is stagnant.
It’s absolutely great for log analysis.
It works fine, but does not have that many bells and whistles.
It’s multiplatform, and can run on Linux for stability and reliability.
Make sure to check out QgroundControl , another great multiplatform GCS.
