On paper these two are close. Both are tour drivers tagged Low Spin, both come in 8°, 9° and 10.5° lofts, both have an adjustable hosel, and both ship with the same Fujikura Ventus Blue 7 in x-stiff or Ventus Blue 6 in stiff. The real split is head size and price. The PXG Lightning Tour uses a full 460cc head, while the Callaway Quantum Triple Diamond is a compact 440cc. A smaller head is usually the more workable, less forgiving option, so the Quantum Triple Diamond suits a player who shapes shots and wants a tighter look at address. The Lightning Tour gives a low spin player the same shaft choices in a larger footprint, which usually means more margin on mishits. The Lightning Tour lists at $499 against $649 for the Quantum Triple Diamond, a $150 gap.
For most golfers shopping this category, the PXG Lightning Tour is the better buy. It matches the Callaway on loft, hosel and stock shaft, adds a larger head, and costs $150 less. Pick the Callaway Quantum Triple Diamond only if a 440cc profile and the extra workability that comes with it matter more to you than forgiveness or price. If neither of those is a priority, the price gap decides it.
