(I used to do a lot of web development and probably know dev tools better than most people here. However I almost never look at the DOM of a webpage I don't own)
There's always some things about practically all websites are frustrating. I fix that with custom CSS and/or Javascript that runs when I load specific sites that I use frequently. I can turn a cluttered site into a streamlined site for my needs. I also block a lot of ads, popups and other annoyances this way.

I wouldn't highly object to either but if I had to pick one I'd definitely clear the former.
„What do you do all day?“
„Looking at the DOM. Currently there are too many divs, but the situation seems fine.“
