These descriptions are terrible and few if any fit. Scalia was not an originalist, dominionism doesn't fit as a judicial philosophy, establishment conservatism has no meaning in a judicial context, and proto-originalist is useless as well.
Gorsuch's past work indicates he'll be a legislative supremacist and probably a textialist. Therefore, Scalia is the closest answer.
Legislative supremacism is not textualism, and Gorsuch is neither.
Somewhere between Roberts, Kennedy, and Alito. Gorsuch is clearly an independent thinker and may very well be a supporter of the judicial ideologies of federalism. I believe he considers each case on a case-by-case basis as well. Overall, rather similar to Sandra Day O'Connor with less ideological factors.
