What is the best Ad/ Tracker blocker for safari IOS? - sh.itjust.works

So currently I’m using 1 Blocker, but I also have tried Adguard as well, however my experience between the two is very different. Adguard for some reason makes searching on safari slow, it may be due to too many rules being set but I’m not entirely sure. 1Blocker runs great and doesn’t affect safari performance in anyway. However I’m looking to see what everyone else’s opinions are, and maybe some suggestions on any other iOS ad/ tracker blockers. I’m mainly looking for open source or trust worthy apps that respect privacy. Thank you for any responses in advance
