The Titleist GT2 / GT3 / GT4 and the Callaway Quantum are dead even on overall Every18 score (97 each), so the decision comes down to how they differ underneath. The Titleist GT2 / GT3 / GT4 is both the cheaper buy (about $425 used vs $560) and the stronger value pick, which makes it the safer choice if budget matters. The Callaway Quantum is the more forgiving of the two, which is the bigger deal for most mid- and higher-handicap players. Bottom line: choose the Titleist GT2 / GT3 / GT4 if you fit its profile (seamless thermoplastic speed); choose the Callaway Quantum if you lean toward tri-force face speed.
