well.. I have the Brick and all the European CD+DVDA sets and I can safely say, as pretty as the Brick is, I much prefer the 2-disc approach of the individual releases (5 of the 2-disc sets were from Warner and 3 released by EMI.. a bit like a Super Mario & Sonic The Hedgehog collaboration.. unlikely.. almost unthinkable.. but brilliant when it happens!) over the DualDiscs in the Brick.
there is greater flexibility over what you can do with the two separate discs (as ever an advantage of CD/DVDA combos over DualDisc) but in this instance the packaging of each set is that bit nicer, the Brick discs are in unique white plastic jewel cases with blank rears so there are no rear inlays, which is unusual but not my cup of tea.
ok so for the purposes of the QQ Polls, there's no difference between the Brick and CD/DVDA sets as far as content, surround mix and fidelity go, etc.. but for the reasons of convenience, flexibility, aesthetics etc I prefer the individual 2-disc sets.. though that's not to say I'd give the Brick a "9" and all of the individual releases a "10".. oh dear.. what point was I trying to make!?
