Take off the Swedish bias and take a look at Silfverberg and Stone you have two guys who are putting up similar NHLE numbers in their respective leagues.
Silfverberg is also a year and a half older so you need to compare how these guys are doing in their leagues and in their development/age.
Then dock points off of Stone for the World Jr "small sample size" bias.
In the end it's pretty much a wash and personal preference between these guys. A lot of "I saw him good" enters here as well.
