Is jimmer fredette or kemba walker better... or shelvin mack?

I have only watched two Jimmer games which were BYU vs Wofford, and BYU vs Florida. And i am watching the uConn vs Arizona game right now, and have seen a couple other kemba walker games. I do not follow college basketball outside of March Madness. From what i have seen Jimmer seems like much more of a ball hog and i have seen him pull up for too many contested threes, while i see that Kemba passes the ball much more, and is also a proficient shooter, and fantastic at driving.. I like Butler and Mack was just so awesome at driving and spliting defenders
