I am getting tired of having to defend myself here. I would say it again, I DO NOT study at the University of Manchester.
The Big 8 idea, if you read my previous posts accurately, was to rival the US Ivy League.
I don't care which universities come out to be the top 8 universities in the UK. However, the most accurate picture that can be used are the world rankings such as QS and THE.
Both rankings consistently put the 8 universities mentioned as the best 8 universities in the UK. For diversity purposes, here is the 2018 list.

I think it is stupid to argue that UCL does not compare to the Ivy League, there are 8 universities including Cornell and Brown, UCL is clearly better and ranked higher than both on international rankings.
Like I have written, if it is Big 5, 6 or 7, it does not matter. It was just a group that can truly rival the Ivy League in the US. Obviously, universities that may be subjectively better may not be on the list such as Stanford, MIT, Berkeley and Caltech in the US.
