Laminated necks are absolutely stronger and less susceptible to twisting / warping. I find them aesthetically pleasing.
It's in the way the grain in each layer opposes the other. It makes a stronger neck.
There are many studies similar to this one on the interwebs. What I never see are studies showing the opposite to be true.
ABSTRACT:
"The neck of guitar is a mechanical structure with a complex geometry which involves many operations and technological solutions with minimal materials consumption, and providing rigitdity to maintain the strings tension during the playing. meeting these requirements is an ongoing challenge for manufacturing because the wood used in the structure of the guitar neck is different as a speicies, as a structure, as physical-mechanical properties and rheological behavior. The paper containing mahogany-maple-mahogany and others containing masarnduba-maple-masaranduba. The samples were subjected to the three-point bending with different intensities of loads (400, 800, 1000, 1400 N), determining for each maximum deflection and the maximum stresses. It was found that the use of laminated wood increases the rigidity of the guitar neck and the bending resistance; the most advantageous combination is masaranduba-maple-masaranduba."
"Keywords: solid wood, glued laminated wood, guitar, three points bending, stifness, beam of constant strength"
RESULTS AND DISCUSSION
"Analyzing the values of maximum displacement in the force direction, it was found that samples from solid wood presents the greatest deflections, regardless of the applied load , which is about 120..250% higher than values obtained on laminated wood samples made from m asaranduba with maple (Fig. 4 a, b). This indicates that guitar neck stiffness can be increased by using a combination of least two wood species"

Another angle on this...just got on a LoPrinzi tenor, with a sandwiched (laminate) neck. The depth of the neck is thinner than most, so I assume the laminate neck provides additional strength, although I see some LoPrinzis without it.
