Man, I don't even like to think about any of them leaving. I will be inconsolable if we lose any of the remaining four.
I miss Christine like I would miss an arm, but if nothing else, I'm happy she's happy. Listening to Homeward Bound, it's hard not to think about how much of her life she gave to touring, perhaps without enjoying it.

That said, if we remove the emotional component, I do think she's more key to the sound than Mick or John. If we're basing it on the music alone, I could whittle it down to the three writers.
