I personally use Adguard home on my home network but I also have nextdns on my personal devices. I haven’t had issues with either of them. Both have pretty similar interfaces, Nextdns was easy to set up and I self host adguard home so it’s a tad more complicated. I have to say nextdns offers a lot more blocklists though, ended up only using a few of the blocklists I’m familiar with because I ended up blocking google and facebook stuff that broke some websites. But that’s more of my fault for not reading which blocklists I turned on than a nextdns problem. Though, it would help if they were to put warnings on potential blocklists that tend to break websites.
