What ads bother you? (Patreon)

So I was playing around with Youtube's options today, and I decided to try various ad types with one of my other accounts.  As far as I am concerned, I actually find the "unskippable" 7 second ads much less annoying than the ones that only let you skip after 5 seconds.  I also personally have never cared if an add was shown after the video was over.

But as I grow my channel, I want to ensure you guys are not annoyed - after all it wouldn't exist without you all!   I will never put mid-roll ads in videos (unless they are old and super long).... I hate ad breaks.  But what is your opinion on "unskippable" ads?
