robot_localization vs ethzasl_msf

edit

I try to choose between these two approaches to implement a multiple sensor fusion, and I researched a bit to figure out their differences.

My sense is that they have similar features, except that ethzasl_msfsupports also intra- and inter- sensor calibration, while for robot_localization there is support also for ROS2. Please correct me if I am wrong. So, is there any other reason to choose robot_localization over ethzasl_msf, except for the ROS2 support?
