I accept your challenge!
I run one of these on my hi torque impact to install cover plates

Personally, I just use a Klein 11 in 1. Square drive when possible, slotted when not. Doing a lot of receptacles, i'd rather carry less from spot to spot. Thought about the Dewalt gyro many times though
I hear ya! I have this Klein shoulder bag (have pictures of it here somewhere) and it just weighs a TON. Good for carrying my tools to the site, or from my truck, especially when my hands are full, but not something I could wear working for more than a few minutes.
What I do now is, I have a couple rubbermaid janitor carts I push around with my tool bag and all my outlets and boxes or whatever on it.
Im not a pro electrician, but maybe like the OP, doing more than one or two and it helps me to have the right tool for the job. I can take more pics of my kit if you guys want to see. It’s not impressive, like some guys have here, just basics.
FWIW, about to turn 60. I’m in good shape, still running occasionally. I’m tall and have always been strong. But I guess I’m slowing down. Don’t love wearing tool belts for carpentry or anything else. So I’m finding ways to stage tools and hardware that limit my need to carry that stuff on my personhood. Walking around is one thing, climbing ladders and scaffolding is another. Lots of things take me longer now I guess. As a young marine, I could run with my ruck and rifle. Now I don’t want to lug around my cell phone!
