What Hacker News says

They're not really comparable. Ka-Block actually advertises itself as being less effective than uBO. It's selling point is that it's a simpler extension that blocks fewer ads and trackers, under the assumption that this is good enough and on it'll on average be faster because of the reduced overhead. > Some ads will get through this filter, and that's ok. We already have extensions that block every ad that's ever appeared on the web with a completionist zeal that must be admired.[0] If you're blocking ads just to make pages load faster, Ka-Block is probably fine. If your primary goal is to protect your privacy, you shouldn't be using Ka-Block. [0]: https://github.com/dgraham/Ka-Block

I suspect it's because there are too many to pay attention to in these short articles. There's 21 listed at http://www.loopinsight.com/2015/09/16/a-list-of-content-bloc... and it's probably not a complete list. Purity, Peace, Crystal and later 1Blocker were all day-one appearances, so they got the most coverage, including here on HN. There's even a long list of open source ones -- and having just looked into this now, I'm thinking of switching to one of these: https://github.com/krishkumar/BlockParty https://github.com/yene/CBlocker https://github.com/saagarjha/OpenAdblock (will work on iPhone 5 and 5C, it claims) https://github.com/dgraham/Ka-Block (for Safari on OS X) https://github.com/jlnr/SansFonts (kills web fonts on iOS)
