AdBlock Plus is available for Chrome and NotScripts replicates NoScript. I'm not sure what BetterPrivacy gets you that you can't do yourself by changing your cookie settings.
However, the author of noscript has said that it isn't technically possible to entirely replicate all of the features of noscript on chrome because extensions on chrome don't have the same kind of access as they do on firefox.
NotScripts is still only mitigating JS and not fully blocking it, at least last time I looked at the source (I also almost puked). Plus it lacks feates like clear click (anti clickjacking), ABE etc.
