Is Durham actually good?

It's better than all but a tiny few, so yes it is good. Very good, in fact.

Nowhere near as good as the "big O"? Well, isn't that pretty much a given since the only other comparable university in the entire country is the "big C"?

I'm also wondering the same thing as have an offer for Law. Stupidly didn't apply for Oxford Law (as I didn't think my LNAT score would be good enough but it was much better than expected) so am considering whether or not to accept the Durham offer or take a gap year (which I wouldn't mind doing anyway) and applying to Oxford. I've had mock Oxford interviews with current students and they've gone well so I have the same question as OP and also whether it would be a good idea to take a gap year.

I would would affirm what fec1864, especially after reading and knowing so many people who had amazing stats on admissions tests, a genuine passion for the subject, critical thinking, amazing personal statement who I thought would definitely get in to be rejected post-interview. Over 10 people applied to law at Oxbridge in my school and none of them got in just because it is so cutthroat and competitive. Oxford law is especially competitive and the selection process can just be so arbitrary (because it’s difficult to choose between so many amazing candidates) that it is just really risky. But this is of course just one side to the story and based on anecdotes but I would highly recommend that you do your own research before deciding on what to do

This is true, but also I wouldn't want to discourage people from applying just because it is so competitive. After all, people do, of course, get in.

Given anon's circumstances, however, I would probably overall caution against it. Getting into Durham for law is an achievement in itself with an acceptance score of just ~30% for home students, one of their most competitive courses, and would put them in a very good position for jobs afterwards. A high LNAT score is by no means a guarantee of an offer at Oxford. It is but one piece of the puzzle, so to speak.

May I ask if no disadvantage for applying newly with a gap year, given that you didn't apply at Y13? In other words, your case is not reapplying. Can Oxford consider reapplying and newly applying with a gap year in a same manner? Are they going to ask why not applied before etc?
I'm considering newly applying for science related subject.
