Prestigious Uni or Normal Uni with my preferred course.

York and Nottingham are also very prestigious universities.

Go for the one you prefer the course of. They're all Russell Group, so I don't think prestige is to much of a concern.

Edit: Lancaster isn't Russell Group.

Lancaster is not a Russell Group.

If it's prestige you want, I'd say either go for Nottingham or go for Exeter

I heard from many people in my country that Exeter and Bristol are much more prestigious and well-respected than three others.

Do the course that you want to do, don't do something you're not so keen on just to get into a "better uni".

I cannot say what is true for how these universities are perceived in your home country but in the UK there is very little to choose between these 5. Certainly it would be difficult to make a case for the idea that any one of these 5 is "much more respected" than any one of the others.

If I were pressed to say which two of these five were marginally more respected here (to the extent that this even makes sense) it would be Bristol + one other. But that other wouldn't be Exeter.
