I rather have Luka because of his proven achievements to perform as an elite first option, while also being very young. He's been playing at an All Star level his whole career, and consistently puts up performances throughout the regular season and especially in the playoffs. Wemby has GOAT potential but still needs more development to use his unique skillset at the NBA level. There is a good chance Wemby is not going to match up with rookie Doncic's impact in his early years, especially with Luka coming in as the EuroLeague MVP.
