That JBL models sensitivity is 90db/ one watt /one meter

That is pretty efficient and from the specs I got from the Brystons
(excellent amps by the way) either would work

The 3bst is rated at roughly 160wpc/8ohms and the 4bst is rated at 250wpc/8ohms

Stereophile did a nice review on the 3bst if your interested

A loudpspeaker with a 90db rating is not power hungry
If it was like 84db then I would say ya ok.........
Also, choosing the amp is how much you want to spend? How hard are
you going to drive these loudspeakers?
Both considerations...If you want to push at higher outputs then
of course you want more power
