Differences between targets and semi in the UK

So I know we often say uni over course but I was curious as the extent to which this applies. I see how Oxford/LSE history is better than maths at Edinburgh/ Bristol. But would this apply for lower targets like Warwick where a Warwick history student is better than an Edinburgh/Bristol economics student? Curious as for most courses places like Warwick in general are the same or even weaker than many of the semi targets, take Durham for example which is objectively a better uni than Warwick for most subjects.
