Best National Trust Properties to visit near Ashbourne, Peak District

[Calmomiletea]

Heading to the Peak District, staying near Ashbourne and we have NT membership..
Which properties are must sees?!
Hardwick Hall?
Lyme Park?
Shugborough?
Kedleston?
Calke?
Museum of Childhood?

Any others?!

I've seen Hardwick, Kedleston and Calke.

Hardwick and Kedleston are wonderful, and I've always wanted to go to Lyme and Shugborough.
As for Calke, they've left it in an unrestored state to show how it actually was when it came in to the Trust - interesting idea, I guess, but I didn't enjoy it.
