If you had to pick one amaro

So I'm gradually building up my home bar stock and experimenting with flavours. I've yet to do anything with amaro (I'm not counting Campari and Aperol).

I tend to go for rye, rum, and gin based drinks. Jungle bird, negroni, old fashioned, dark and stormy, sours/gimlets/daiquiris are my cup of tea.

If you had to pick from these 3 only, which ONE would you go for? And what would you recommend I try using it in?
