2021 Irons
The Srixon ZX4 / ZX5 / ZX7 and the Cobra DARKSPEED are dead even on overall Every18 score (97 each), so the decision comes down to how they differ underneath. The Srixon ZX4 / ZX5 / ZX7 is both the cheaper buy (about $510 used vs $800) and the stronger value pick, which makes it the safer choice if budget matters. Bottom line: choose the Srixon ZX4 / ZX5 / ZX7 if you fit its profile (mainframe forged matrix); choose the Cobra DARKSPEED if you lean toward modern distance.
