Quick Verdict
On the hard QS metrics, it's a genuine split: IIT Bombay leads on academic reputation, employer reputation, and faculty-student ratio, while IIT Delhi leads on citations per faculty and international research network. Neither institute dominates outright on faculty and academics — the winner depends on which specific metric matters most to you.

Detailed Analysis
IIT Bombay holds a clear edge in academic reputation (73.3 vs 67.9) and employer reputation (96.7 vs 95.0) — both scores reflecting how the institute is regarded by peer academics and hiring employers surveyed for the QS rankings (Times of India). Bombay also has more international faculty proportionally (6.5% vs 3.2%) (Times of India).
IIT Delhi, meanwhile, scores meaningfully higher on citations per faculty (93.1 vs 82.9) and international research network (66.9 vs 46.6) — both signals of research output and global collaboration reach (Times of India). Delhi also has a slightly larger faculty body overall (816 vs 772) (Times of India).
Zooming out to the IIT system as a whole: IITs generally maintain a faculty-to-student ratio between 1:6 and 1:8, well above the IIT Council's own minimum requirement of 1:9 (Wikipedia) — both Bombay and Delhi operate within this well-resourced band relative to typical Indian engineering colleges. IITs as a category also receive substantially higher government funding than other engineering institutions, with per-institute annual funding running ₹900-1,300 million ($19-27 million) compared to just ₹100-200 million ($2-4 million) for most other engineering colleges (Wikipedia). Neither institute's government funding is subject to direct control over internal academic decisions like faculty recruitment or curriculum — that autonomy sits with the institute itself, with government only holding representation on the IIT Council (Wikipedia).
Verdict
Split verdict, no outright winner. IIT Bombay wins on academic and employer reputation plus international faculty diversity; IIT Delhi wins on citations per faculty and international research collaboration reach. If reputation among peers and recruiters matters most to you, lean IIT Bombay. If raw research output and citation impact matter more, IIT Delhi has the edge on those specific measures.
