I would say Nottingham Trent is more respected than Plymouth. But it depends on what you want from your degree, Plymouth is know for its art related degrees, so if your art is a strong point I would choose Plymouth. From what I've heard about Trent they have just upgraded all of their equipment and so it has really good facilities which would obviously be useful for the degree, and is a good sign for the quality of the teaching of the degree. But I completely agree that these two are by far the best, if you can achieve the grades go for Plymouth of Trent, depending on which you would feel is right for you.
