Whilst they are useful for framing an argument, i wouldnt read to much into any individual stat. They are very subjective and different media organisations give very different measurements of the same stat. E.g. FoxSports had Brooks 23 try assists in 2021 and Doueihi 16.Shoutout to @WesternSuburbsBoy on the stats. It's good to see.
Also that metric is what has happened on typically one play in an 80minute performance. There is 79 other minutes of game time to worry about and many other subtleties of performance that aren't recorded in publicly available statistics. For example, i find Brooks is one of the better halves in the league at getting his lead runners one on one with an opposition defender. But there is nowhere i could look this up to confirm this.
There is really no way to measure best. It will always be observation and opinion.
