I wanted to like pihole so much and ran one in my home for a while. Unfortunately I had to move back to per-device adblockers.
I had multiple instances of sites just not working because of the pihole was blocking something. This would result in me putting it in non-block mode for a little bit, rinse and repeat. I can't have that kind of hassle when non-technical people use the internet too. At least with per-device adblockers it's a single click to disable/enable the adblocker if a site is acting funny.
Basically, it wasn't any faster than just blocking ads on the device itself & added another thing on the network for me to manage.
It’s literally changed my internet experience in my home.
