I voted One Tree Hill.
First time U2 used a sample loop for the intro ? Which makes it quite early in their discography.
Vocals are a masterclass. Bono gives his full range.
Great syncopated bass line, which is something Adam rarely does.
Awesome drumming, with Larry alternating cowbell and hi-hat. I have yet to hear another drummer pull the same trick and make it work.
Huge dynamics throughout the song.
That outro… my goodness. Just pure beauty.
Also worthy of interest is what’s, to me, the best live version :
