There are (and remain) significant differences between integrated and modular courses - the rules have not been changed. that is a different point from your employability as a graduate. My opinion is that it does make a difference as a fresh graduate, ie without any post-graduate experience. However, the difference dissapears when experience is added.
As to the original question about league tables, there is no published evidence to support the many and colourful opinions you'll get here, but historic reputation would make the top league BAE, WMU and OAT, with SFT joining Cabair in the second league. There are modular schools which do not offer the full range who would warrant a top league place for the modules they supply, eg Bristol Groundschool.
Do the top league deserve their placings? Should the second league be promoted? I hear the noise of that can being opened again!
