Mizuno mp 62 or nike victory red split backs?

I am debating which set of irons I want to get. I have played the Nike procombo irons for a couple years now and am ready to get new ones. I love nike irons but I heard the feel on mizunos is amazing. I am a decent golfer shooting low 80's and looking to take a step up in clubs. just trying to see if anyone has swung wither clubs and their opinions. Thanks!
