The biggest difference is how hard each one fights a slice. Most testers found the XXIO 12 has a mild draw tendency, and one found its flight fairly neutral. Testers agree the XXIO Prime has a clear draw bias. That correction can be strong enough to send open-face misses well left.
The Prime is also the lighter and longer driver. In the 10.5° model it weighs 254g in total with a 184g head and is 46.5 inches long. The XXIO 12 weighs 282g with a 199g head and is 45.75 inches long. Testers say the Prime's length takes some getting used to. Both are premium-priced drivers for slower and moderate swing speeds, and reviewers say both launch high and add distance.
Choose the XXIO 12 Driver if…
you swing at a slower to moderate speed and want easy distance and launch with only a mild draw tendency, in the heavier (282g) and shorter (45.75-inch) of the two.
Choose the XXIO Prime Driver if…
you fight a slice and want the stronger draw correction and the lightest build (254g, 46.5 inches). You should also be ready to adjust to the extra length.
