A number 1 WR should be able to beat a # 1 CB frequently and double coverage on occasion
Doubs best trait is route running - and you can win with that
Reed's best traits are shiftiness and route running- you can win with that too
However, Watson has elite athleticism that neither of those guys have- so he is the most likely to ascend to the role of # 1. I don't think Doubs or Reed can handle that challenge at this point in their development. MLF is scheming them open and they're utilizing their skills to take advantage.
If Doubs/Reed were treated to a steady diet of # 1 CB and /or double coverage- I'm not convinced they could win often enough to be considered # 1 WRs. It took Davante Adams awhile to reach that level through tons of reps and dedication to his craft because he too lacked elite athleticism.
We haven't seen the ceiling of any of these WRs yet, but from a physical POV, Watson seems like the best bet

Watson was superior to his D2 competition, so he didn't need to master the nuances of playing WR. The first time he had to actually fight somebody for the ball was when he got to the NFL...and now he's much better at it. Same thing with not letting the CBs push him towards the sideline on go routes - in college he just ran by everybody, but in the NFL, these guys have hands on you the entire route. Watson is by all reports a hard worker/good student- and given time & reps- I believe he will become a consistent, potent threat worthy of the # 1 moniker
The injuries stunted his development timeline, but not his ceiling imo
