We used Luxardo Fernet, and found it VERY Fernet-forward. Fernet on the nose before sipping, first sip shows the bianco and Galliano, and then it's Fernet again for the long, long finish. Great if you love Fernet, good if you like Fernet.
Decided to make it my first time taking into consideration previous comments. So: 1:1:1 of Navy strength gin (Chemist, from here in Asheville NC USA), Punt e Mes, Cynar. First sip: smooth, with subtle (compared to Negroni) bitterness...and then delayed-reaction POW!! from the Cynar. Nice, and fascinating the way the Cynar hits in timed-release fashion.
