I have adblock on my primary chrome profile, but occasionally browse using a profile where it is disabled because [reasons]. My experience has been generally pleasant if you discount the low-quality ads that would be blocked under this new scheme.

Instead, I get ads for interesting new components on DigiKey or Mouser, or the similar, and I find myself clicking on ads several times a week because I'm genuinely interested in what I see -- it's like a news feed for unusual devices.

Imagine if your Twitter feed was served several tweets at a time embedded in other sites you regularly visit. You could argue it's a distraction, but but it's far from unpleasant. "Personalized ads" work a lot the same way for me.
