I have Armstead slightly higher b/c I really like what we have catching the ball with Waddle, Wilson, Gesicki and Edmonds. I think people are sleeping on Wilson. Like Hill and Waddle, Wilson was also among the league leaders in getting separation. When he was pressed into the starting role in Dallas last year he looked like he belonged there. Arguably, he often looked like their best WR. I was just watching the Brett Khollman/EJ preview and they were saying that they had Wilson rated about equal with Tyler Boyd. I don't think people realize how good of a signing that was.
What I was surprised about with Hill is the example he provides with how hard he works in practice. Reports from OTAs are rife with comments about how fast Hill practices, moves from drill to drill, etc. Stuff like that pushes other players to try and match him. That's invaluable and raises the effort of everyone around him.
