Every once in a while I’m at someone else’s computer and phone where I don’t have a pihole and adblockers everywhere, and it’s just a nightmare experience.

I have no idea how people live like that… It makes the web unusable to me.

uBO is certainly one of the best adblockers and I have always used it, but I also use Trace as an excellent complement, which covers the privacy holes that uBO does not cover. https://absolutedouble.co.uk/trace/
