"The best glue" depends to an extent on how you will prep the gluing surfaces. Will they be planer-smooth, ground coarsely in a lam grinder, surfaced with a toothing plane?
Some glues have gap filling properties and others don't. Pair them wrong and the bow's chances of delamination increase.
Personally, I use Smooth On for most everything nowadays and prep the surfaces freshly ground from my lam grinder, or the toothing plane (usually used on bamboo, risers, overlays, etc).
