It depends on what you're hoping to get out of it. I mostly-whole-ass it, but I still use the mac app store and homebrew for a few things. Most projects are Nix by this point.
It's hard to tell from how you say it; if you aren't using it for any projects and would just be using it for a slice of your system/user packages, I suspect you'll end up not really seeing what the fuss is about. If you will try to use it with some projects, I'd start there and see how it goes.
(It should be fairly low stakes. If it doesn't stick, you won't disrupt yourself that much. If it does stick, you'll have a better sense of what you want to hand over to it and why.)
