I don't know if I buy that both are playing for Sweden, since Max himself played for Germany in a U17 AAA tournament just last year. Though its not a IIHF sanction event, it could mean where the player stands for the international level. I mean I wouldn't be shocked if they decided to play both play for Sweden, but to be honest I don't know if they are good enough for Sweden. A couple years ago, I would say both are promising, but now Max has sort of not lived up to a bit of that hype IMO. His numbers aren't bad for the Superelit, but NHL quality forwards that Sweden produce are above PPG as underagers in the same league. Magnus looks like the more interesting player since he's easily better than anything at U16, thus why he's in U18 Elit. And Sweden doesn't have high enough big centres? They have De La Rose and 193 cm Olhaver which Avs drafted over this summer. Honestly, I think the country who asks them first is going to get their rights. They can definitely play more if it is for Germany than being scratched/injury options for Sweden.
If they do decide to play for Germany, I think both can be some really good depth options for tournaments, which Germany have severely lacked (talent on the bottom 6 lines). I must admit, a lot of players that Germany are starting to develop are looking like it has been the best since the country has gotten into hockey. The defensive talent is worrying since all their NHL defenders are on the wrong age, but forward wise, it has been a step in a the right direction concerning talent.
