PiHole is fine, I guess. I'm not a huge fan of it personally because:

  - It's local network only, and while I can VPN home, I don't always want to
  - It has a high maintenance overhead, at least for me. It would block too much, then my wife would complain, and I'd have to spend time figuring out the magic rule that was breaking.
  - It's DNS-level blocking only, which is helpful but doesn't cover nearly as much ground as just uBlock can. 
  - The DNS server has annoying preconfigured caching rules, that, while I can work around, it was just more effort for something I don't want to put more effort into.  

It's far easier to just install uBlock and tell my wife, if something breaks, just click the red shield icon, then click the giant power button.
