I actually like a lot of them, and they've improved a ton since the start in general.

I'm fine with measuring performance, and sometimes tailoring content, but prefer to opt-out of ad targeting and offline matching.

Most all of them are missing proper opt-outs that really should be there, however it's a good start.

Thinking about it, the one I have the most disdain for is The Guardian's; it has a quick UI but the accept-all button is labelled "Yes I'm Happy".
