Never felt much for many of his other songs either. I hate Psycho Killer.
That's very high praise.
With all respect and sincerity, I'd love to know your age and music listening background. While I, too, enjoy the song, it's definitely not in my top 100 of greatest songs ever written.
Perhaps you and I have nearly identical musical listening histories, in which case I 'high five' your pick for #1. Absent that, I can't help but think there are some songs you've not heard.
There are certain objective measures, e.g. Top 5/10/25/100 lists by critics and other credentialed people. There are record sales and polls and now, thanks to streaming, "listens". Yes, each of these have an element of subjectivity to them but also certain patterns become apparent, such that particular songs and artists show up again and again across the various measures.
As an aside I read that fela kuti was an influence to eno at the time and I think that can be heard in the repetitive nature of the song, especially in the guitar lines.
