I do find the Guardian table interesting, not necessarily in a "good" interesting way though.
The 2016 CUG is also now out, and presumably the Sunday Times one will be out shortly too. Guardian seems to have a massive downer on Bristol - 35th ranked overall, compared to 15th in CUG, and Liverpool another RG which the G ranks as 59th, although it only manages 39th in CUG. Conversely it is clearly in love with Coventry ranking it 15th, compared with 48th in CUG and to a lesser extent Falmouth 31st (eg above Bristol apparently
) which CUG ranks 70th.
But for most of the more prestigious Unis the overall placements are remarkably similar, identical rankings for the likes of Cambridge, Oxford, Loughborough, Southampton, Edinburgh, and only a couple of places different for St. Andrews, Durham, Warwick, UCL, Exeter, Lancaster, Birmingham. Both tables also both agree on London Met as lowest rank. How far this similarity extends into the subject tables I don't know, as being somewhat biased I only looked at what DS1 is studying - both G and CUG agreed on placement and I imagine ST will follow suit on that one.
G also appears to have a few Unis missing as compared with the CUG, and even has lost one from its own 2015 rankings (Canterbury Christchurch).
The individual subject tables may be slightly more meaningful but even then I think liberal doses of salt are probably needed.
Still I imagine they keep the Uni marketing departments in overdrive :)
