I really think you are under rating Luko because of the roles he has been played in so far in his career by Stuart DewI think you are way under-rating Ben King due to his poor from so far this season off an ACL. Lukosius is a very good player, but he is a square peg player - you have to find the exact right role and right opponent for him. King you don't have to shuffle anything, he just goes straight in as a key forward. He was good enough to average around 2.5 goals + goal assists in his 3rd season before doing his knee, and in a weak team.
King's career to date is a bit inconclusive and even barring the knee he is probably not tracking as well as Tom Lynch to the same point of his career. Lynch is the cream for aerial key forwards though. To me the potential looks to be there with King. He should imporve as this season progresses and next year we can really start to judge him.
Lukosius is showing himself to be a great goal assist exponent. But he is a bit of an uncontested beast at this stage, so is not going to fulfil the sort of key forward role we would normally want.
Interesting pair to track. But at this stage I would back King to be a more seamless fit for us in future years.
Play the man at CHF and leave him there and he is very much a Jeromy Cameron level player and can play multiple roles
