No, I don't.
First, most apps' code won't run as root. Only install scripts, written my distribution's maintainers, run as root (except for core applications, of course).
And secondly, I trust app developers to write their app properly (to a certain extent), but not to write install scripts that won't mess with my system, because it's outside their domain of expertise.
Install Chromium on Linux Mint and you'll have code run as root that is not written by your distribution's maintainers. Because Mint won't ship the snap, and nor are they shipping a deb that they maintain. You'll have to install a third party deb or equivalent.
This brings up another drawback of deb/rpm packaging, though: you need root access to install anything. I'm not sure about Snap, but Flatpaks can be installed and used by an individual user.
