The biggest difference is what each driver is built around. The TaylorMade Qi4D is the all-round, adjustable core model. Its four movable weights let you shift the centre of gravity toward a draw, a fade or a more penetrating flight, and testers found its spin consistently mid-to-low. The Titleist GTS2 is the stability model in its line. It has the largest footprint in the GTS family plus front and rear weight ports, and testers disagreed about its launch and spin.
Testers say both hold ball speed well on heel and toe strikes. The GTS2 has a classic glossy black look and is aimed mainly at mid-to-high handicappers, while the Qi4D suits a wider range of players. Specs: Qi4D 45.75 inches, 56° lie; GTS2 45.5 inches, 58.5° lie.
Choose the Qi4D Driver if…
you want to shape your ball flight toward a draw, a fade or a more penetrating trajectory with four movable weights, and you want spin kept in a well-controlled mid-to-low window.
Choose the GTS2 Driver if…
you're a mid-to-high handicapper or a less consistent ball-striker who wants the most stability and a large, classic glossy black head at address, and you don't mind paying a premium price.
