I hadn't heard this until you bring it up here. I found this quote, which I find interesting.
I recently replied to a JW on
/r/TrueChristian about how they believe that Christ is the chief angel in heaven. The infamous controversy is they believe that there is only one archangel and that it is only Christ. I brought up how Daniel 10:13 calls Michael "one of the chief princes", and from that I noted that there must be more than one chief prince, thus there is not just one as they claim.
But when I looked at the commentaries of this verse I found something that surprised me:
John Wesley: "Michael here is commonly supposed to mean Christ."
John Gill: "and is no other than Christ the Son of God, an uncreated Angel; who is "one", or "the first of the chief Princes""
Geneva: "even Michael, that is, Christ Jesus the head of angels."
And then I looked at the Wikipedia article for Michael, and at the
Protestant section it states:
Citing Hengstenberg, John A. Lees, in International Standard Bible Encyclopedia, states: "The earlier Protestant scholars usually identified Michael with the pre-incarnate Christ, finding support for their view, not only in the juxtaposition of the 'child' and the archangel in Rev 12:1-17, but also in the attributes ascribed to him in Daniel."
Charles Haddon Spurgeon, a Trinitarian, stated that Jesus is Michael “the only Archangel”, and that he is God the Son, and co-equal to the Father. In Spurgeon’s view, "archangel" means "head of the angels" rather than "head angel," and is a title similar to "Prince or Leader of the host." (Daniel 8:11)
