I have a z-suit, and I like it real well. I don't know about the Crain suits, although I have considered getting one because Ricky's gym is only a couple hours drive from my house, and I thought I could get him to size me personally. Ricky sold me my first bench shirt umpteen years ago. He is a really nice guy, and he will reply if you contact him on goheavy.com
Good luck.
