> Any ranking I’ve seen recently generally has it right up there.

Really? Hm.

The listings I've seen, and the first I found, were UK-focused ones, which put Oxford and Cambridge in the top two, sometimes with others as joint-second, then after that Imperial, e.g. https://www.timeshighereducation.com/student/best-universiti...

But to support your claim, I did just find an international ranking that is confusing me by giving rankings for 2026, and for 2025 and 2026 puts Imperial before (and previous years, behind) both of Oxbridge: https://en.wikipedia.org/wiki/QS_World_University_Rankings
