Reus might be classier than Bale, but I don't know about "better". Bale has proven himself. Reus really hasn't. They'll both score and assist wherever they go. Bale seems fit more often than not, Reus is a bit injury prone. That's the way I see it anyway. It really depends on how the team is set up and what you need from them.
In fact, I'd have Reus and Bale in the same team, no problem.
