I don't know about +/-, but for anyone who has actually watched a few games, it is obvious that Mavs are Luka's team, much like the Suns are Booker's. It is also obvious that the kid is already an amazing player and Booker comparison is fair, in good ways and bad. They can both get good shots from anywhere on the floor, against anyone guarding them. Both force a little too much, and the more they facilitate, the better they facilitate, but their shooting percentage goes down.
Ignoring Booker's rookie season, the two look very similar when we look at Booker's second season and Luka's rookie year. Booker was a little bit older, but I think Luka's professional experience makes up for that, making this a fair comparison. Booker is a slightly better scorer, Luka is a better facilitator. They both turn the ball over a bit. Luka is slightly more efficient.
Can't figure out how to get the table to show up here, but here is the link:

Here is some information:
Booker vs. Doncic
Minutes: 35 vs. 32.4

EFG%: 47.5% vs. 50.2%
FT%: 83.2% vs. 77% on 5.7 attempts for each
Fouls: 3.1 vs. 2
Now, I am not an expert on advanced stats, but here they are:
TS%: 53.7 vs. 55.7
PER: 14.6 vs. 17.7

Bottom line is that Doncic is already an amazing player. There is just no rational way to argue that he is not.
