The TaylorMade Qi4D LS and the Callaway Quantum Triple Diamond are close on paper. Both are 2026 tour drivers built for 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. Both carry a $649 MSRP. The one hard difference is head size. The Qi4D LS is a full 460cc head, while the Quantum Triple Diamond is 440cc. A smaller head is usually easier to shape and less forgiving on off-center strikes, so the Callaway suits a player who wants to work the ball and finds the center often. The larger TaylorMade suits a low-spin player who still wants some margin for error.
If forgiveness matters more to you than workability, pick the TaylorMade Qi4D LS. The extra head volume is the only spec that separates the two, and it favors the golfer who mishits now and then. If you shape shots on purpose and prefer a compact look at address, pick the Callaway Quantum Triple Diamond. Price, loft choice and stock shaft do not tip the decision either way. Feel is the tiebreaker, so hit both if you can and let your hands decide.
