I think it's worse for me, based on the current set. The official trending page has a few videos that I'd like to watch, including two from my subscriptions. But the fairtrending page has nothing I am interested in.
I’m reasonably sure the YouTube one shows old stuff if it’s currently popular. Which I’d assume is what you’d want.
There’s nothing is even consider watching on the “Fair trending” one; I can see myself watching one or two things off the YouTube one if I was very bored.
