The creators of Digimon tend to give the angelic/Devil type digimon hella powers ahead of the other types of digimon.
I also find it weird even though Angemon is champion and Angewomon is ultimate , Angemon still betters her in the anime series.
She has had troubles with ultimates and mega a like.
Angemon has done well with Ultimates , and has at least harmed Megas for a bit.
Then MagnaAngemon appears and the rape party begins.
