Laminated is better, by far.

another quotation came up which is best quote

Option A
10mm glass
Option B
9.52mm laminated glass (1.52mm PVB sandwiched by 4mm heat strenghted glass)
Option C
22mm clear glass w/ airspace (2x 6mm clear glass with 9mm airspace in between)

*thanks john for replying. why is the laminated better than the 10mm glass even it is less thicker??

The laminated layer provides decoupling, killing some of the vibration that is more readily transferred by solid glass.  In the new scenario, option C might be as good (or better) as B, but what would really be best is as thick as glass as possible with as big as an airspace as possible...
