Cilic is a good and very complete player but he has no big weapons. He is basically a worse version of Murray. To succeed playing like Murray you really need his talent and tactical mastery.
Wawrinka, on the other hand, can do big damage with his groundstrokes.
Are you sure you've watched Cilic play regularly, especially his best matches? His FH and BH are both very big shots, as is his ROS - I don't have stats with me, but merely from observation I'd say that he gets more winners per match on average than guys like Del Potro (this I'm sure of) and Berdych, although far more UEs too. Not to mention Cilic plays nothing like Murray - he's an attacking big hitter.
Wawrinka, no contest.
Yup. Cilic is 4 years younger and has done better at Slams and won more than 2x titles. He's also higher ranked currently. There's no doubt Wawrinka is the better player. This could have nothing to do with 'Also really like: Wawrinka Dislike: Cilic', could it
? Only edge Wawrinka has in this comparison is his performance at M1000 level.
