<p>Since this is an undergraduate forum, I think we should focus on the undergrad level. And at this level, people seem to be debating three distinct things: (A) Difficulty of admissions, (B) Quality of the education, and (C) Reputation.</p>
<p>For (A), it is meaningless to look at admission rates/yield, since the US and UK employ such different application systems. What we should look at, is the size of the applicant pool vs the number of places available. Harvard has roughly 1,660 per class, while Oxford has around 3,200. Given that the US population is 5 times that of the UK, it looks like Harvard has the edge here. </p>
<p>Some may argue that the Oxford system of academic interviews, etc. is more rigorous. I would say that the British and American schools are simply looking for different things. And it doesn’t matter if Oxford makes applicants do differential equations while juggling ten cats and balancing a bathtub on his head and eating fire at the same time–it still has to take 3,200 kids every year, from a more or less set number of A-level leavers. So numbers-wise, Harvard is way more selective than Oxford.</p>
<p>(B) is where the tricky part comes in, as the two models are so different. Simply comparing the rigor of curricula is useless, as one can argue that, under the American system, motivated students who take graduate classes and conduct cutting-edge research can go equally in-depth in one subject, if not more so. And how do you compare the benefits of the Oxford tutorial to the more rounded liberal arts curriculum and more extensive research opportunities American students enjoy? Not to mention that some students simply fare better under certain systems…</p>
<p>(C) Reputation is even harder to gauge, and I suspect it varies greatly depending on the social circle one finds himself in. It’s really pointless to talk about this. </p>
<p>As for comparing Harvard and Oxford on their research prowess, I believe the crown must go to Harvard. Almost every single ranking based on overall research quality has Harvard placed ahead of Oxbridge. I am sure Oxford has a sterling reputation, but if we look at the numbers, Harvard wins.</p>
