Which Two Diamond Shapes Look Best Together in a Toi et Moi Ring?

I'm looking at different Toi et Moi rings and noticed there are so many two-stone combinations. Some have pear and oval, while others use emerald, marquise, or radiant diamonds.

I found this collection while searching:

If you could choose any two diamond shapes, which combination would you pick and why? I'd love to know which one you think looks the best.
