I just bought the Park pliers for opening and closing quick-links, because the kid's new bike came with a SRAM 12-speed and their version, which I think they call a power-link.

I then noticed Shimano sells a version of their XTR chain (which I use) that has a (presumably genuine) Quick-Link for an extra $3.

Is there any downside to this? Does it weaken the chain? Does it wear stuff out any quicker? Does it shift less smoothly, cause infertility, projectile diarrhea, cancer, heart disease, premature Alzheimer's, or other potentially negative side effects?

I broke my ankle a few years ago and am a bit irrationally paranoid about snapping a chain when I am climbing a steep hill.
