I concur with Daveyf that a home trial is the best way forward, or at least try to listen to both speakers if possible. Both options are excellent and a lot of factors as mentioned earlier(associated equipment, room, listening preference) will come into play when deciding which one is more suitable.
To balance out the enthusiasm on the Extrema, here is a short excerpt on the Guarneri Homage on page 4 of Stereophile's review

It's rare to find a speaker that's truly balancedwith a tonal, harmonic linearity that extends from the upper bass to the high treble. In this respect, the Guarneri eclipses the other Sonus Faber designs. The bigger models, particularly the Electa Amator and Extrema, will play louder, are more dynamic, and have better, deeper bass; but rarely is a speaker as truthful to its source as the Guarneri.
