Which Ad-Tweet do you find most effective?

Which of these ad types do you find most effective when you’re scrolling away on twitter? And which of them do you think works worst?

Promoted Tweets - the annoying unwanted tweets in your feed
Promoted accounts - other than showing accs in the timeline, twitter will suggest some people to follow in the “who to follow” section, these are those.
Takeover ads - the trend and timeline pages’ mass awareness generators
Twitter Live - you know...

Also which have you as an advertiser and not the audience found to be the highest conversion?

How would you know which of the above is where these new followers come from?

I was thinking more of new followers, retweets etc. But guess he may mean traffic to his website.
