The prettiest Echeveria of all is:

Echeveria lindsyana

Echeveria lindsyana

Wow! If I didn’t have a nursery, and thus have a whole bunch of these Echeveria lindsyanas already, I would for sure buy that.

Some facts for you: From Mexico, as is typical of these Echeverias in the Crassulaceae Family. Hardy into the lower 20s, but probably not all the way down to 20F. They will form small dense clumps of 6″ rosettes. And they’re pretty. Oh so pretty. They feel pretty and witty and bright! And I pity any Echeverias who isn’t lindsyana tonight!
