They are very complementary. Cases, lugs, dials, size... I really like the 5970P and its strong black dial.
I also love the king of cool 5070P.
The 5970P, as you said, looks more serious. But not less charming.
In an ideal world such as yours, getting both is the way to go.
With the Vacheron Malte Chronograph, one of the nicest QP / Chrono, in my opinion.
Enjoy this delicious duo, my friend.
Best,
Nicolas
