I'm using the combination of these browser add-ons available for Firefox and Chromium: uBlock Origin uMatrix EFF Privacy Badger uBlock Origin is an ad blocker. uMatrix is similar to NoScript but a lot more flexible and easier to use, and comes with some hosts files (not copied to /etc/hosts). And Privacy Badger blocks domains, JavaScripts, cookies etc. that are used to create a profile of yours. Those three are doing quite a good job from what I can tell. And surfing on a Raspberry Pi 3 is also a lot better with these. That said, it's not only ad servers which cause a massive CPU load, it's also badly designed and overloaded websites which contain a lot of JavaScript and load content from several other servers, particularly from JavaScript hosts and CDNs.
