Best blocker and the one I'm using now is uBlock Origin. I hardly see any ads on any site, although some sites require me to disable the ad blocker for access to the site.
Ghostery is available for the iPhone as a browser. I use it on my desktop where its a plug in to Firefox- in that case it blocks 'trackers' that report your activity to other sites like Google. As a browser on the iPhone it acts a bit different. You have to set it to block trackers- when you do it works a lot better (and faster) but not all sites will resolve. Audiogon does FWIW and I don't get any redirects or popups. Ghostery also blocks ads. This is really nice when active on forum sites that have a lot of ads. It loads faster and seems less annoying :)
