On paper, the TaylorMade Qi4D and the Mizuno JPX One are close to identical. Both are 460cc players distance drivers with an adjustable hosel, both carry the High Launch tag, and both ship with the same Fujikura Ventus Blue 6 in stiff and Ventus Blue 5 in regular. Two things separate them. The Qi4D offers four lofts, 8°, 9°, 10.5° and 12°, while the JPX One offers three, starting at 9°. That 8° head matters to faster swings that fight spin. The JPX One lists at $549 against $649 for the Qi4D, so it saves $100 at full price.
If you swing hard enough to need an 8° head, or you simply want the widest range of loft choices, the Qi4D is the pick and the extra $100 buys something real. Everyone else should take a hard look at the JPX One. It matches the Qi4D on head size, adjustability and stock shafts, covers 9° to 12°, and costs less. For most golfers the choice comes down to whether that 8° option is worth the price gap. If it is not, the JPX One is the better value.
