I don't know if White is the better WR, but I believe he'd be the better WR for the Bears. I've thought & still think the speed element at the WR position would really make this offense scary.
When I think back to when the Bears has Knox & Hester, they had the speed but they didn't have the talent. Now they do have multiple receiving targets that can get the 50/50's & batter DB's underneath. I believe if the Bears were to add a kid like white to the existing talent on the offense I kid like White would thrive.
I think back to Willie Gault. He wasn't a great receiver. I still believe he was a better athlete than football player. But when I look back at that team, great defense aside. the offense had an efficient enough QB to win with, a road grater O-Line, excellent running game, solid TE with Moorehead. As a result of having that key talent already established Gault, the Bears were able to beat a lot of teams down the field at key moments, & Gault in a sense was able to produce beyond what his pure ability as a football player may or may not have portrait.
I think adding a WR with both burner speed & talent, would make would be an excellent addition, especially with already having other legit talent on the offense, & when the Bears do add a new QB it should only help make their development that much easier.
I'd take White with the Bears built as they currently are
