I had a conversation with someone I know (Dr A)recently about different universities. I have been trying in a small way to get more support for some students to apply to Oxbridge (and also other Russell Group universities). This person works for a non Russell Group uni. They said that Oxbridge no longer has a cachet - they were very disparaging about it - and that they would specifically discourage their own DC from applying there and that it was widely accepted that other unis were better. They thought that students got less individual teaching by experts at Oxbridge than at other unis.
I thought this was a bit odd, but might be their own individual opinion. I would think that generally, OB was a good idea to get into, if you can, on a have-a-go-but-don't-pin all-your-hopes sort of basis, and then RG was a fairly good idea to pursue; American unis might be fantastic if you can get the funding; other unis might be superb especially if they have a particular course that excels or a tutor who you know is interesting to you. And different settings of course suit different people.
I have studied and taught (in a very junior way) at an OB uni and also studied and taught at other RG unis. I also did a course for work at at non RG uni. My experience suggested, boringly, that OB>RG>non-RG for quality of teaching, support and so on. However, we are talking of patchy, anecdotal experience over 40 years here (as I am long of tooth) so my undergraduate experience for example is very out of date.
Another person who had heard this conversation later said that their partner, another academic of much experience and seniority, agreed with Dr A. So I wondered what the thoughts are on here. And also, how to get objective data to substantiate either point of view?
