@technomancy Right, so, you can definitely nitpick the individual things (and lots more, obviously), but it's not one of the things, it's really all of them together.
On the package side, I don't think there's really anything that compares. Example, I sometimes (but rarely) need to use Chrome or a Chrome-derived browser, for things like "somebody sent me a Google Meet invite and I don't have ten minutes brainspace to convince them it should work in my weird browser again today." I *never* want to open anything else in it, ever, and even having it installed risks something thinking it ought to open something with it.
Being able to install and run it, then bail from that shell and have it be gone is awesome as hell, and there's not an analogue of that in Debian -- you have to set up the package source and repo signing key, `apt update && apt -y install google-chrome-stable` and then remember to uninstall it afterwards. Just a whole bunch of ugh right there.
