A lot of the things you're talking about here are correct, but not entirely relevant. Matri has good instinct. I feel like this year is unfair to judge him because of getting used to Conte's tactics. The possession game doesn't suit the prototype centre forward. He needs to be either physically adept to run from very deep or a more hybrid kind of player with ball skills. Higuain according to me, will have the same problems Matri currently has in this set up. He may score more coz he's played at a higher level for much longer, but I don't think he will score as freely as everybody thinks.
when surrounded and played right, matri is very usefull for any team, especially in form.
Higuain, was real madrid at his first year. better impact then ronaldo that year, superb finisher, allways in form, very technical and unlike matri, can lead the attack regardless of the playstyle
matri is a poacher at best, higuain is a complete forward with better finishing then matri.
of all the forward we talked about, higuain certainly is the most clinical. exactly what we need.
