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".
