Wanted to get opinions on how you guys like to bond a #10 equipment grounding conductor in junction boxes and device boxes.
Bonding 10 Awg conductor in boxes

Ground screw and a #10 tail to splice to the other EGC's. If there is only one #10 EGC then connect it directly to the ground screw. If there's a receptacle use a self-grounding device.
I use fork spade connectors to connect the #10 to the box. That makes some inspectors get bent out of shape.
For the most part I install an additional pigtail to connect to the device. Otherwise use a self grounding device if the box is tight.

I like what Infinity said, but whether dealing with solid or stranded conductor may make some difference also.

I don't know. I have heard it all and none of them make sense to me:
- Not designed and listed for grounding purpose
- Not designed for building wire, they are for fine strand
- Need to use a regular chair lug
- .....
Most of the time when I challenge them they back down.

First trick to working with 10AWG is to use stranded. Once you do that life gets better.

With NM you generally have no choice but solid conductors.

Yet solid wraps a screw with no problem so I will stick with solid.

I have issues with the code on this issue. #10 ground works fine for breakers up to 60 amps. So my #6 cable can use a #10 ground. But my #10 cable cannot use a #12 ground pigtail.. (unless you are me and nobody is looking that close. Nyuck, Nyuck. )

Im surprised they don't make #10 ground tails...they are all #12
Or you can use a nut driver.
To each their own but imo those ready made tails, much like "greenies", are mainly a gimmick and another largely unnecessary part to be hauled around. You can simply use the excess egc at the boxes for your tails- roughly the same install time and cheaper too.

installed in an impact driver or drillOr you can use a nut driver.
Depends on the circumstances. Do you regularly have enough excess conductor at the boxes? Do you have some 12 solid bare readily available - that with some greenies may be fastest with least materials cost, otherwise regardless of what you are using, they cost more if the foreman is installing them then if the apprentice is installing them, assuming the apprentice gets it right the first time.

I prefer to make my own, those store bought 6" tails are just too short for my liking. We use mostly 2 1/8" or 2 1/2" deep boxes and 6" long just doesn't cut it.

When I'm making up quad covers (2 duplex in a raised Industrial cover) triple pig tails really save time.
A lot of electricians feel #12 pig tails are good for #10
