Probably Power of the Daleks ep6. That and Evil are the stories I'd most like to see, but Power is entirely missing. Having at least one episode back, gives the animators some reference to work from in restoring the rest. The telesnaps alone must be really difficult for them.
One of the missing Celestial Toymaker eps, because I think that (with the obvious exception of Mission To The Unknown) then going by the "only two missing ep" rule that's the only find that would make another serial eligible to be completed with animation.

Oh, wait! :cool::D
I'm going to have to pick a new one...
This, followed by Daleks' Masterplan 12. Also would love to see The Massacre for Hartnell's dual role.

Not a bad choice, Ben and Polly's farewell.
