Well, I do Religious Studies and Classical Civilisation and I completely disagree with everyone else...
Classical Civ is so immensely popular with the top, redbrick universities - Warwick, Durham, Oxbridge, (it's a nice old boys subject like Latin or History) and there is a lot more to grasp than English Literature and Religious Studies combined.
In my Classical Civ course, I have to know 8 plays [4 for AS], 2 novels [1 for AS], 3 architectural sites [2 for AS], including buildings contained and, (the three worst) 14 black figure, 17 red figure vases [AS only] and 68 pieces of sculpture [A2 only]. All the art/architecture has names, dates, uses sculptors and museums to remember.
And Religious Studies is seen as a doss subject, even though we know it isn't. Philosophy isn't seen as such, but is generally much easier than Classical Civ.
So Classical Civ all the way, although it's a subject that you can only do greatly in if you truly immerse yourself in it, which is why most people who do Classical Civ go on to do degrees in it. (I'm the exception that proves the rule)
