I know this is late but I did a PiHole for years as well. But then I needed another solution for being out of the house, and my housemate later complained they wanted to see Facebook ads…

And like the other poster my gateway didn’t work with a a pihole so I had to change each clients’ DNS (which reverting for the housemate was a solution).

It was worth it but ultimately I needed more than just a pihole, sideloading my iPhone every week with custom YouTube apps, trying to find a custom twitch app to sideload, having to use Yewtu.be on mobile, etc. None of the apps like Adguard blocked ads in other apps well enough from what I experienced.

I wish I'd been able to get the pihole to work as easily as it sounded. It looked cool. But it was incompatible with the router from the ISP I had at the time, and rather than also buy and setup a new router, I just packed it away. Now I have a new ISP with a different router, and I'm sure it's incompatible too.

But at least it only takes 30 seconds to install ublock origin, and no extra hardware.

I don't have PiHole but this instead https://someonewhocares.org/hosts/ on all laptops.
