It's stable enough. I haven't noticed any problems since it was installed.
Enabled me to solve production problems faster or even avoid them preemptively with warnings.

Ability for system diagnostics
I also really appreciated all the work that everybody did to get it functional for JES3, and they continue to do so, even though IBM said they are going to do away with JES3.
