I self-lower everything that I can, mostly light riggging. Over time, I have found it safer and easier. I don't find the climbing/ rigging/ cutting to be very challenging most of the time, so I have bandwidth to focus on the rigging, too.
A less complicated day for a groundie can add up to more work done.
Reg said not to trust your life to other people. I have remembered that for years, now.
There are times were you work with a competent, professional, skilled ground workers, and mostly laborer groundies, who oftentimes are plain labor for a reason.
