For those who don't know, Request Policy (RP) simply blocks requests outside the website's domain. I configured mine to deny all requests unless I whitelist them (by hostname). It eliminates most security issues; Ghostery rarely has to block any trackers, for example.
I would never recommend it for a typical end-user; it requires too much understanding (e.g, to understand enough about CDNs to identify which hosts need to be whitelisted). For most people reading this, it would be no problem.
It comes with large, pre-configured whitelists that cover many common websites. Many sites work fine without anything whitelisted, though most need at least one host for their CSS. More complex sites, such as those running applications, can take some effort to get running. Once you figure out a site, RP remembers the whitelist and the site works indefinitely.
The interface needs work but it's functional. There is a beta of a new version, which is supposed to fix some interface issues, but I haven't tried it.
Adblock Edge is not known to have such issues, as of yet.
Personally, I'd rather call the usual +/- 20 background requests per page (of which each company may track you) "intrusive". But I suppose that's a matter of preferences.
EDIT re: Adblock Edge instead of Adblock Plus:
Adblock Plus has sold out, taking money for unblocking certain ads.
The other two however, go for them, they're not intrusive to the user experience at all in my experience.
Is there a reason why you suggest Adblock Edge instead of Adblock Plus?
