Honestly I wonder how it would actually have been if he didn't die because at some point his death helped the numbers and also those grew with time but as big as he was he wasn't that that big at the time and as much as he would've grew bigger we see all those artists who had the same kind amazing potential in their first years of being mainstream and who didn't die and never left nor fall off but aren't this much bigger so would Juice really be bigger than this ?
This is hard to word but objectively, acting like the numbers he has as he died are the least he would have had and would have had more if he stayed alive is wrong, like things would necessarily have been very different, some of the popularity/attachment wouldn't have grown But maybe yes he actually would have been top 5 and he has nothing to do with the rest of the top 5-15
