I would prolly pick Mizuno....I hit new miura cb57 today and they were nice...Also hit cb5 and an older blade....miura is more "special" in a way cuz you don't see em around very much and they cost more... but from a pure standpoint of just hitting irons side by side I think Mizunos feel better....for sure they feel softer, but since mizzy is more mainstream people will pick miura I am sure....
For a club you cam walk into any store and buy Mizuno is hard to beat and don't forget Mizuno is a Japanese forged club!....so it is in JDM category...and they feel awesome.....my buddy has new MP4 irons and what a great feeling stick....I was hitting his side by side against miura cb57 and mp4 felt better....The miura is a beautiful head though....lil firmer more powerful feeling, I actually liked it alot and look at address was stunning....fairly easy to hit as well.....
But I think if I was spending $1500 plus on a ser I would buy yoro craft set!
