I like Davis and see him as one of the higher upside players who could be available at 9. He's a good shooter despite of his inefficiency for all the reasons explained in the OP. He was a one man show and had to do everything on both sides of the ball and he was also hurt, he could have sat and preserved his stock but he toughened up and chose to play for his team at the cost of a million scouts blaming him for his late season struggles. Coaches love players like that.
My only issue with him is that he couldn't get to the rim at all despite of his good ballhandling and footwork. He didn't have any spacing to work with but it's still a concern, he settled for too many contested midrange Js.
That said, he has an ideas skillset for the modern NBA - he could be a good roleplayer due to his intangibles, defense, effort, toughness, spot up shooting but he could also grow into a major scoring threat with his ability to create for himself. He has everything a team needs from a perimeter player to be able to stay on the floor during the playoffs in today's NBA.
I like Daniels too but there are concerns with his shot, he projects are a high lever roleplayer, whereas Davis has more upside. The problem is that if both end up as roleplayers, which is the most likely outcome, then I consider Daniels the better one. But higher upside is always tantalizing
I think it's similar with Duren vs Williams.
