My favorite so far is the standard 1:1:1 with Plymouth gin and Cocchi di Torrino vermouth.
The earthy / leathery qualities of the Plymouth and the spicy qualities of the Cocchi work nicely. I haven't played with Pune e Mes yet. There are of course too many combinations of interesting gins and vermouths to try in one lifetime. Attempts to do so may even shorten said lifetime.
