I don't know what the argument is about. We've had both of them play for us. We should just be happy about that, that in 40 years time, you'll be telling your children that you saw such brilliant strikers play for the club.
We had a great striker. Sadly we lost him to injury. But we now have another, who continues to bring us joy.
So just catch the match on the weekend, and enjoy Shev's skills, and after that is over search for a few replays of Marco's goals over the net

There really is no reason to squabble. It just serves no purpose.
