while its awkward to compare their playstyles, they can also be compared from an effectiveness relative to teammates angle. Hey, I compare the three of them all the time.
from what I can see mainly following Lekkerimaki from afar.
Lekkerimaki- He is hands down the team MVP. the team is not really a playoff team if he didnt will them into the playoffs. They have an anemic offense. If he bulks up a bit and learn to attack the middle more, he is a lock for a top 6 winger with his shot alone, that consistently beat SHL goalies from distance.
Ostlund- playing for a powerful side, Ostlund was on the third line producing decent numbers. playing around 13-14 minutes? I am lukewarm on him actually, I think he is a good skater for sure, and he was certainly good in the WJC, but he doesnt have that dynamic quality that can overtake Cozens and Thompson and gel with a pretty offensive top 6 in Buffalo.
Ohgren- also playing for the top team that is scoring at will. He is a contributor, good mobility, even uses his body and just more noticeable in one late Feburary game I saw that had him going head to head with Ostlund's Lakers. Too bad his year was marred by injuries, but I came away more impressed with him, I think he can at least contribute on a 3rd line role with his smarts, he should be a versatile guy.
