Wayne is a much better traditional rapper. He doesn't only have bars but he has a variety of flows and is capable of outshining many types of rappers on songs, including actual lyricists like Benny.
But his catalog is generally mid. There's some highlights like Carter 2 and his mixtape catalog but the rest of his albums has generally aged almost as bad as Eminem's catalog. The rest of his albums have good songs sprinkled in like Go DJ, A Milli, Let The Beat Build, etc. but Carter 2 is his most cohesive project that actually can be compared to other classic/quality rap albums.
And that was always Wayne's weakness. He could spit like his life depended on it but he wasn't good at making consistent and cohesive albums.
Future is a worse rapper than Wayne. I don't care what ya'll say. Future is carried by delivery, not lyrics or flow. But he's better than Wayne when it comes to putting out cohesive albums and having a decent level of consistency for the type of music he does.
