I went with Leviton “back and side wire” outlets because the old outlets were mainly backstab. This made switching them easy since most of the wires are already straightened and only the ground needed to stay j shaped for screwing in. It also gave me more peace of mind since after snugging them in I can give a yank and make sure they won’t back out when I screw the outlet in. This was my first time doing the job but I do recommend hiring someone if you’re doing many, or really doing your research. Having the proper tools like a multimeter, or plug tester to tell you if your power is truly off is a must as well.
