Bert is a different player, not easily comparable. Bert is an energy guy who fits anywhere up/down the lineup.
Thing is though, from what you read about Ras's game, he seems to be doing well in his own end, puts up some points and will be an asset on the PP. So while they are stylistically different, Ras seems to me as a guy who can slide up and down the lineup and work in various roles, especially if he gets stronger than he was as an 18 year old.
I will admit, because he is in a lower league, I was hoping he would lead the league in scoring by a decent bit, as the league he is in is well below the AHL or SHL and similar. That said he is playing in an unfamiliar place, with people who speak a different language, which can make on ice chemistry and communication harder for many.
