More often than not I'd use more space to get all the op-amps
> connected together than in two duals.


Right - and even the two duals will only take 8/7 to space
of a quad.

Of course the quad's multifold symmetry can be of advantage
for some layout situations, too. I often try 3 variants
for opamp layout, and see which one fits best: 

Quad
Dual DIL
Dual SIL

You will be surprised how easy layout can be when you
go for SIL packages! Too bad that they are not very common,
often more expensive, and generally restricted to japanese 
opamp types.
