Diffusion takes place much more quickly with gases than with liquids or solids. (CHEMISTRY: A COURSE FOR 'O' LEVEL, by Christopher N. Prescott, page 9. The emphasis is mine)

Diffusion takes place much more quickly with gases than with liquids AND diffusion takes place much more quickly with gases than with solids.

John is taller than both of them, therefore I would use "and" but that is because I have written a lot of computer code where you have to be precise about using "and" and "or" operators. Colloquially both are acceptable in that sentence.
