Do you guys use feed through method( connecting right to terminals) or pigtail/splice the conductors to the terminals? Thanks

I like unbroken loops around EGC bonding screw for use with self-grounding devices.

If possible avoid wirenuts with unbroken loops around device terminals otherwise limited to 4 wires.

Where 300.13(B) applies, ugly wirenut keeps line-side neutrals connected without relying on device terminals.

Pigtails always. I might make an exception for an old box that is already stuffed with wires.

Those conductors are almost always pigtailed, via solid, to devices that have only screws.
I've been looking for 15 amp devices with pressure plate terminals.

2 slots per screw for existing #12 wire is really nice when no room in box for wirenuts. The pressure plates also work for stranded, if you hate to twist & wrap around screws.

With the typical 2-cable install, I use the device terminals. If another cable is added, I'll pigtail, and put the new conductors on the device's terminals.

Most premium-grade receptacles, such as Leviton Preferred, have a clamping feature.

Pigtail with backwired clamping receptacle. Now, as others have said, if there is not a lot of room, or maybe really old and brittle insulation or some other circumstance, I'll use the device.

Why do most of you guys pigtail(besides qty wires in box)? isn't it easier and quicker to terminate at the device terminals?
Depends, with a self grounding receptacle you only need to land 2 wires on the device which makes it easier to push it into the box especially with #10 wire.

Thanks. So what do you do with the ground wire if you have a ground wire e.g. MC cable? Also, why would you ever use #10 for standard 20A receptacles?
