The biggest gap between these two players cavity irons is loft. The Mizuno JPX 925 Forged runs a 30.5° 7-iron against 34° on the Srixon ZXi7, a 3.5 degree difference that works out to roughly 8 yards more carry at the same swing speed. Set makeup differs too. The Mizuno covers 4-iron to AW, so a gap wedge is built in, while the Srixon runs 3-iron to PW and adds a long iron instead. The ZXi7 is also the only one tagged Progressive Lofts, Vibration Dampening, Forged and Cavity Back, and it lists for $50 less at $1,149 MSRP versus $1,199. Editorial scores are close. Golf Digest gives both 78/100. MyGolfSpy rates the ZXi7 at 86/100 and the JPX 925 Forged at 84/100.
Pick the Srixon ZXi7 if you want the weaker lofts, a stock 3-iron and the lower price. It costs $50 less and carries the higher MyGolfSpy score. Pick the Mizuno JPX 925 Forged if distance is the priority and you would rather have the AW in the set to keep wedge gaps tight. Neither set has a feel advantage on file, so a fitting settles that. On price and ratings alone, the ZXi7 is the stronger buy.
