Re: Mizuno Vs SrixonI'd say of the two brands, Srixon is a touch ahead.
Srixon takes the woods category. Srixon's Cleveland brand makes very good woods, notably the HiBore and Launcher. Mizuno's woods (including their titanium fairways) are more expensive, are not nearly as well regarded.
Neither brand is known for their hybrids, but a slight edge goes to Mizuno for its Fli-Hi hybrid irons, which are very nice.
Irons is a wash. Both brands make fantastic forged irons. Mizuno has a slight edge in variety, but both brands make forged game improvement, players, and blade type irons, although Srixon's blades are very rare.
Wedges goes to Srixon, their Cleveland brand's 588 and CG-12 are among the most popular wedges ever made. Mizuno's wedges are good, but not as highly regarded as Cleveland's wedges.
Putters are more or less evenly split, with Srixon's Cleveland and Never Compromise line both producing great putters, and Mizuno's Bettinardi producing equally fine putters.
Balls goes to Srixon, as Mizuno doesn't make them. Even considering that, Srixon balls are second to none.
